“Crushology 101” keeps serving up chaos like a late-night snack you can’t resist. In episodes 3 and 4, our heroine, Hee-jin, finds herself at the center of a love square so tangled it might need its own GPS. Two very different guys vie for her attention. One is a chaebol heir with a poker face. The other is a student council regular whose nervous energy is sometimes endearing, sometimes cringe. Meanwhile, a famous sculptor flirts with Hee-jin on the side, just to mix things up. By the time credits roll, alliances have shifted, secrets spill out, and our girl weighs whether her next romantic move is worth the risk.
If you thought episode 2 was dramatic, buckle up. We’re diving into betrayal, a locked room, and a private eye who moonlights as a relationship guru. Along the way, we’ll unpack key moments, take a closer look at power dynamics, and explore what Hee-jin’s journey tells us about modern dating. Plus, stick around for my personal perspective on who deserves her heart and why this drama is anything but a “nothing burger.”

From Shirt Drama to Lockdown Panic

The Shirt Incident That Refuses to Die
Long story short: Jae-yeol, our awkward yet oddly charming student council rep, steps up with a confession. He still wants to see Hee-jin. Why? Because she never returned that oversized shirt he gave her. Cue collective eye-roll. Hee-jin hands it back on the spot and reminds Jae-yeol that their “thing” ended. Yet fate (and the writers) insist they’re stuck together at a crucial meeting for department reps.
…and so, we return to the hallway of second chances. Hee-jin has a new task: interview Ah-rang, a sculptor whose masterpieces adorn galleries worldwide. He’s also notorious for ghosting journalists. Naturally, he shows up on campus just when she least expects it.

Flirty Sculptor and Jealous Bystander
When Ah-rang saunters in, he’s all smooth charm. Hee-jin mentions the interview; he grins. He’s in. Meanwhile, Jae-yeol watches from a distance, his cheeks coloring like a ripe tomato. Ah-rang’s pedigree? Top-tier celebrity artist. Ji-won’s pedigree? Chaebol heir with deep pockets and deeper secrets. And then there’s Jae-yeol—a regular student whose biggest qualification is a tragic backstory straight out of K-drama school.
His mother’s latest beau gets prime time over him. He’s got abandonment issues and zero chill. We’re supposed to root for him, but honestly? He sometimes feels like a walking emotional support commercial.
Trapped in the Closet (Literally)
After the interview, Hee-jin and Jae-yeol stay late to tidy up. Plot twist: they get locked in a storage room with zero cell service. Perfect recipe: small space, no help, and Hee-jin’s stomach decides now’s the time for drama. Cue hemmed-in panic and a hammer-wielding rescue. Jae-yeol busts the lock. Hee-jin’s relief is palpable. Cold shoulders thaw into genuine smiles. For five glorious minutes, they’re just two students bonding over bad ventilation and digestive distress.

Pajama Parties and Private Eyes
Sister-Zoned at Sunset
Ji-won, the cool chaebol oppa, swoops in with an invite: a pajama party with Hee-jin’s crew. She says yes. At dinner (catered by someone who clearly has unlimited funds), the girls debate whether Ah-rang’s studio invite is code for true love or a midlife crisis. Ji-won, unruffled as ever, offers sage advice: Hee-jin will know Ah-rang’s intentions when the moment arrives. He sounds so calm, you almost forget he’s secretly nursing feelings of his own.
He’s so polite. So reserved. So classic second lead it hurts. He’ll play the supportive friend again, and then—if he doesn’t step up—lose her to a dude with a better pick-up line.
When Jealousy Calls in Backup
Speaking of backup: Jae-yeol and Ji-won forge a flimsy truce. Their target? Ah-rang. Rumor has it, the sculptor nets college girls like Pokémon. Jae-yeol uses his editing skills to snoop on Ah-rang’s amateur podcast interview. He listens to a snippet between Ah-rang and a Hee-jin colleague. Whatever they’re whispering, it’s enough to push him over the edge.
Rather than explain, he drags Hee-jin during her date, lectures her about past mistakes, and storms off. She’s hurt. He’s dramatic. We’re conflicted.
Detective Ji-won to the Rescue
Ji-won, bless his strategic soul, hires a PI. Surprise: Ah-rang has a roster of ten-plus one-night flings. His method? Flattery, late-night studio sessions, and a casual disregard for consent. Once the receipts are in hand, the boys plan a friendly heads-up for Hee-jin.
But the universe laughs. Hee-jin catches Ah-rang in a clinch with another girl before Jae-yeol or Ji-won can intervene. It’s cringe. It’s cathartic. It’s that moment you rewind three times because it’s so satisfying.

The Climactic Showdown and Heartbreak
Bucket of Ice Justice
Hee-jin confronts Ah-rang. His response? “It’s my private life.” Ouch. Suddenly, Hee-jin’s trauma from ex-boyfriend Jerk McJerkface is a handy survival skill. She hoists an ice bucket over his head like it’s the most natural thing in the world. The splash is symbolic. Her empowerment? Even more so.
After the meltdown, Ah-rang’s career crashes. His sponsors—wait for it—are courtesy of Ji-won’s family foundation. He’s dropped. Unceremoniously. Publicly. And deservedly.
Picking Up the Pieces
Heart bruised twice in two weeks, Hee-jin declares a temporary moratorium on boy drama. Romance radar? Totally busted. Meanwhile, Jae-yeol and Ji-won start reading tea leaves to gauge each other’s interest. Ji-won notes Jae-yeol’s renewed closeness with Hee-jin. Jae-yeol misreads cues and suspects Ji-won has snagged her heart. Cue more jealousy.
Confessions in the Rain
Jae-yeol, fueled by soju and regret, blurts out a heartfelt confession: he’s liked Hee-jin since before she even noticed him. Flashbacks confirm it. He’s fallen first and he’s fallen hard. Under neon streetlights (and maybe a drizzle), he begs Hee-jin to stop inhabiting his thoughts. She’s taken aback. But she listens. And that’s a start.
Meanwhile, Ji-won, watching from afar, has a revelation: he’d better hurry or lose her forever.

Themes, Motifs, and Soul-Searching Insights
Power Dynamics and Predators
If episodes 3-4 teach us anything, it’s that power can corrupt even the most talented. Ah-rang’s artistic genius comes with strings attached. He’s a predator hiding behind cultured banter. This isn’t unique to K-dramas. It’s a reflection of how fame and influence can warp intentions.
Second Lead Syndrome
Ji-won’s character arc embodies the painful grace of unspoken love. He’s patient. Polite. Predictable. Too predictable. He risks becoming background music in Hee-jin’s life because his emotional brakes are too strong. Second lead syndrome is real, folks. It’s the fear of scaring someone away by being honest.
Healing by Setting Boundaries
Hee-jin’s ice-bucket moment isn’t just comedic relief. It’s a turning point. She’s been through heartbreak before. This time, she refuses to be the damsel in distress. She wields cold hard truth like a weapon. Her self-worth rises.
Friendships vs. Feelings
Our girl has two guys in her corner. They bond over saving her from see-through relationships. But friendship and romance aren’t the same. Jealousy seeps in. Alliances shift. It’s messy. It’s human. It’s painfully relatable.

My Point of View
Let’s get real. “Crushology 101” could have leaned into cliché territory. Instead, it zigs when you expect it to zag. Ah-rang’s betrayal is brutal but justified by character design. Ji-won needs an emotional wake-up call. He’s been starring in his own silent film for too long.
Jae-yeol’s confession is a highlight. It’s raw. It’s imperfect. His timing is questionable—blame the alcohol—but his honesty shimmers through. Hee-jin’s journey mirrors what many of us experience: fumbling through crushes, getting burned, building walls, and then daring to fall again. That’s the messy beauty of modern dating.
Plus, can we talk about aesthetics? Sunlight filters through cherry blossoms like nature’s Instagram filter. Every frame is a painterly postcard. And Hong Min-ki’s cameo? I’m still waiting, but I’ll be here with popcorn.
Final Thoughts and What’s Next
By episode 4, Hee-jin stands taller. Sure, she’s bruised. But she’s wiser. She knows her value. She knows that not every invitation is sincere. She knows the difference between a heart that beats for her and a heart she’s propelling with pity.
Who will she choose? Will Ji-won seize his chance? Will Jae-yeol refine his timing? Or will a brand-new contender glide in with better lighting and better lines?
Stay tuned. Because if there’s one thing “Crushology 101” promises, it’s that real growth often comes through romantic ruin. And if it leads to a killer confession under the rain, I’m here for every dripping moment.
