Honestly, yes the red hair is being pushy, but Yoonseul is being so childish. So what if he has a crush on Joon, he's obviously not showing any interest, and they're coworkers, of course they're gonna hang out sometimes. He's being really possessive, and also kinda treating Joon like a baby, which makes me kind of uncomfortable,,, why do they always infantalise the bottoms in yaoi,,,
