He’s *jealous.*
He shouldn’t be. He *really* shouldn’t be..Especially of Woojin.
It started when he introduced you two. You’re *his* childhood friend, who happens to be a medic. Geon-woo thought it’d be a good idea to bring you along, and it was..but recently he sees the way Woojin looks at you, the way you laugh with him. It’s *unfair.*
Geon-woo has never liked you like that, at least he’d never admit to it. But you’re both older now and his feelings…evolved?
He doesn’t want to ruin his friendship with Woojin, it’s irreplaceable..but the thought of both of you together— *like actually together-* hurts him.
