Sana is an art instructor when she met her student named Tzuyu. The latter's thoughtful behavior made Sana fall for her. But Sana is too indecisive to know if she really like her or just liking the treatment Tzuyu is giving. Sana always see her as a student who is just being nice to her. Now that Tzuyu gave up showing signs and probably gave up on her, she's been longing for the girl's attention, making her jealous by flirting with different girls around her. Yet, the latter does not seem to care and found a new love.

[Teacher x student] "Love is just a silly, chemical reaction that goes off in your brain to make you think that you love someone but in fact, love is just nonsense and just a waste of time, money and effort to be in a relationship with someone else. I would be a fool to believe in love" Tzuyu is a 17-year-old girl who has everything any girl ever wants, she has beauty, smarts, popularity and money. She was what others would call the whole package, which of course led to having nearly all the students in Seoul High School having a crush on her at some point in their lives. Many tried to pursue her and all have failed, especially since she has her philosophy of how love was stupid and an utter waste of time ever since she witnessed the split of her now-divorced parents. That is, until one day she met Minatozaki Sana, her newest homeroom and chemistry teacher, will the meeting of a new teacher change her perception of love?

Where Sana is Tzuyu's stepsister, and Mina is Chaeyoung's stepsister... A bit different from the one shots

Minatozaki Sana has always been used to being adored. Flirty, spoiled, and breathtakingly beautiful, she knows how to get attention-and she knows she doesn't have to give much back. Her friends joke she's the ultimate pillow princess-a girl who loves affection, loves being touched, but never gives more than she wants to. She's fine with that. Relationships come and go. No one has ever made her feel like giving more. Until Chou Tzuyu. Tzuyu is calm. Collected. Mysterious. She has an intimidating, unreadable gaze and a reputation as a stone-cold heartbreaker. But what no one realizes is that Tzuyu doesn't fall easily-when she gives, she gives everything. She's a one-way top in every sense: intensely focused on her partner's pleasure, never asking for anything back. When their lives cross-maybe in college, a queer bar scene, or through mutual friends-the chemistry is immediate. Sana finds herself drawn to Tzuyu's quiet dominance and laser focus. Tzuyu, against her better judgment, is helplessly drawn to Sana's softness and neediness, even if she knows it might never be reciprocated. They fall into something undefined. Passionate, unbalanced, and confusing. Sana starts to wonder if being cared for this much is enough-or if she's ready to try giving back, emotionally and physically. Tzuyu, meanwhile, battles with the question: how long can she give and give without being seen as someone worthy of receiving?

You know what's hard? When your girlfriend used to flirt with everyone and anyone before. And now, just when you thought everything is settled... a big fight will try to get in between you and will try to destroy you. Will they be able to fix it or let everything go?
