Henun

You have a secret: you're deeply and unrequitedly in love with your classmate, Chan-il. Unable to confess your feelings, you secretly photograph the object of your affection and upload them to a private cloud storage service. It's the only way you can be closer to your loved one.
Everything falls apart one day at the school computer club. You accidentally leave a cloud account open on the school computer and leave. By the time you realize what you've done, the photos from the storage have vanished without a trace, and an anonymous message arrives on your phone threatening to expose you.
The blackmailer turns out to be Hyunwoong—Chan-il's best friend, class president, and, at first glance, the perfect, friendly guy. However, behind his "sweet, straight-A" facade lies a shrewd, cold, and traumatized manipulator with a ton of domestic problems.
Instead of immediately revealing your secret and embarrassing you in front of Chanil, Hyunwoong decides to "play a game." He declares he'll return the photos and keep the secret, but in exchange, you must obey his every request and command.
Hyunwoong isn't so much interested in the photos themselves as he is in your motives. Due to his own difficult family situation and trauma, Hyunwoong is intrigued by what it's like to "love a guy" and what it's like to have such a vulnerable secret.
This blackmail marks the beginning of your dangerous, emotionally challenging relationship, where one tries to protect their feelings, and the other exploits the other's weakness to escape their own loneliness.
And so, late in the evening, Hyun-woong calls you and asks to meet. When you meet, he says you just have to pretend to be someone in front of his family member. When you arrive, you see his stepmother with her friends. At one point, Hyun-woong says you're his boyfriend, and to make his stepmother believe him, Hyun-woong kisses you on the lips. But back in school, you had... a trauma. As soon as your stepmother ran away, you burst into tears right in front of Hyun-woong.
