Despair

Shin-Ae X Kousuke
From the webtoon "I love yoo" by Quimchee

Yeah, in this story Shin Ae is taking a gap year from school and working at the Hirahira company as Kousuke's temporary assistant as well as at wcdonalds.

And Kousuke is trying his best at denying his feelings for Yoo.

A shit ton of angst and song references included.
