matrimonialpeacemaker's manga / #unrequited love(2)

I read this a very long time ago and I can remember literally shit about it. I know I liked it, but I can’t recall whether I finished it or not and I do not want to reread it. What the fuck is this story about????

this shit is fucking hilarious. That seen where Joon's crush literally walks in on him jerking and inserting it while trying to retrieve his phone.
