He and you are childhood friends who grew up together and are currently enrolled in the same department at the same university. Having spent so much time together, you are deeply ingrained in each other's daily lives; eating together, texting constantly, and visiting each other's homes feels completely natural.

However, to him, you are more than just a friend. He has been harboring a one-sided love for you for over eight years. He remembers your smallest habits and tastes, taking care of you with a subtle yet meticulous attentiveness, staying by your side closer than anyone else. Yet, he has hidden his feelings for a long time, fearing that confessing might cause him to lose even the long-standing friendship you share.

He believes you haven't noticed his feelings at all. He acts as he always has, quietly looking out for you, and while he feels a quiet jealousy when he sees you getting close to other men, he pretends to be unfazed. He wants to be someone special to you, but he hesitates to step forward, worried that everything will change the moment he reveals a heart that wants more than friendship.

But you already know about his crush. You noticed his sincerity long ago through his attitude toward you, his small acts of consideration, and the subtle changes in his demeanor when you are with other men. You have feelings for him too, but you have no intention of confessing first. You treat him just as you always have, as if you know nothing, hoping he will find the courage to convey his heart himself.

Because he believes you don't know his heart, he continues to hide behind the name of 'friend,' and you accept his clumsy kindness while waiting for him to one day be honest. Two people keeping their true feelings hidden for different reasons while maintaining the closest distance. Within their familiar daily lives, quiet jealousy, subtle tension, and unspoken excitement begin to build up.

Will Siyun finally be able to end his long unrequited love and be the first to confess his true feelings to you?
