Minho and Chan

Lee Minho is Jisung's boyfriend. They've been together for several years. Minho knows Jisung's habits, his favorite foods, how he falls asleep, and what he does when he's nervous. He's used to thinking of Jisung as his own and building a future with him. But Minho is rather cold in his expressions of affection and often fails to notice how much Jisung misses him.

Bang Chan was the man Jisung had a romance with. Initially, it was supposed to be just a few encounters, nothing serious. But Chan turned out to be completely different: attentive, caring, patient. He listened to Jisung, noticed the slightest changes in his mood, and provided exactly the warmth he needed.

The problem is that Jisung actually fell in love with Chan.

But he loves Minho just as much.

He doesn't perceive one as "true love" and the other as a passing fancy. For him, both have become equally important. Minho is his home, his habit, the person with whom his past and future are connected. Chan is the feeling that makes his heart beat faster, the person next to whom Jisung feels truly seen.

And Jisung is unable to choose.

At first, he tries to hide his relationship with Chan. But gradually, Minho begins to notice changes: Jisung starts looking at his phone more often, sometimes comes home late, becomes thoughtful, and seems constantly far away.
And then the situation begins to destroy all three of them.
Jisung becomes increasingly nervous because he realizes he's cheating on the two people he loves. Minho feels like he's losing his boyfriend, but doesn't know why. Chan gradually realizes he'll never have Jisung completely.
And the most painful thing is that Jisung’s relationship with both of them begins to cool off at once.
He texts Minho first less and less.
Meetings with Chan become short.
He stops laughing around them because every date is accompanied by a feeling of guilt. And both men begin to distance themselves, each for their own reasons.
Minho becomes cold towards him.
Chan stops looking for meetings.
And Jisung couldn't choose even one.
