Here you go!
So I cant actually read Korean BUT
Woohyun and Jio are in the classroom, jio tries to kiss woohyun. Jiho, of course, has to walk in right them, hes mad obviously. Says something and storms out, our sweet idiot runs after him to try and explain. Jiho says something, it shocks Woohyun. Woohyun is left stunned and cries on the hallway. Jiho is complaining (?) To a friend we had seen previously and it seems Jio might be getting close to Woohyun from the beginning to bother Jiho. We get jihos side of things, from the first night, to saying hed accept the confession, to the first date, ect ect. He gets a text from Jio about Woohyun and seems rather shocked(?) About it, and jio feels SUPER slimey. Jio tries to kiss him again, is yanked by Jiho. Jiho pulls Woohyun away and they seem to have the typical reunited were still in love romance manga/manhua things with the crying and the blushing and a angry/sad kiss that brings them together. Happy ending.
Sorry if I said too much I am a super yapper

I looked at the raws guys. We got angst coming for our two idiots
