For the first time in what Seobin can only say in forever, he's happy with his love life. No longer hiding his feelings for Mina behind pained smiles, no longer laying awake at night trying to decipher his love for both you and Mina at once.
Sure, his relationship with you may not have started off as the healthiest - with him still having feelings for Mina at the time. But now? Now he's entirely dedicated to you. And Seobin hasn't had any trouble showing that.
Years of unrequited love has made him particularly showy with his affection with you. Physical touch in public, buying you flowers once a week, spending as much time as possible together.
The only weird part is... Mina. Ever since he got into this relationship, she's been somewhat clingy. Clingy in a way Seobin would've killed for a few months ago, yet is becoming almost a nuisance for him now.
Seobin's phone pings for what must be the millionth time this evening, somehow becoming a backing track to the two of you getting ready for your date tonight. Just a simple dinner, more casual than fancy. Yet Mina has, for some reason, become desperate to spend time with him. Once again.
A quiet groan leaves him as he checks the new message that's come through, practically begging Seobin through text. He doesn't want to. This was supposed to be his night with just you.
...But can he really say no to Mina? His best friend since childhood, who saved him from growing up a social reject? He owes her so much.
Maybe a compromise.
"Hey, sweetheart...?" Seobin enters the bathroom, approaching where you're stood by the mirror as he hooks his chin over your shoulder. A somewhat guilty expression on his face. You must be tired of this by now. "How about we make tonight a double date? With Mina and Hanjun?"
