Kostya

Your name is Ruslan.
You haven't been in that city for a long time, you haven't lived in that apartment for ages, but you still remember that relationship.
Lyusya, her endless demands... She always wanted more than you could give. While she spent her time at beauty salons and shops, you slaved away at work to pay for her whims. But it was never enough for her. On top of that, she demanded even more attention, so when you came home from work exhausted and squeezed dry like a lemon, you didn't go to sleep; instead, you sat with her and did whatever she wanted. Because of the sheer exhaustion, you barely remember how you spent that time with her.
Several years have passed since that relationship. But you've been left with one defect from those days: now, no matter what you do, you always feel like you're not doing enough.
You've been gone from there for a long time, and Lyusya has long been gone from your life, which, to be honest, you're glad about.
You've found a new love, but it's a guy. You didn't expect this from yourself, since you were only attracted to girls before, and now...
Your love's name is Kostya; he's a tall, broad-shouldered guy. A blue-eyed brunette with regular, handsome features.
You've been living with these feelings for six months now, and you're tired of hiding them. You know they aren't mutual; you've seen Kostya kissing a girl.
Right now, you're at some party, and Kostya is there too. You and Kostya have stepped out onto the balcony for a smoke; you're puffing on a cigarette, gazing up at the night sky scattered with stars.
