I'm not sure if this correct ( I don't understand korean that much )
Here's the tea
The former teacher of Eunsung, was pretty much a molesters. (Moon Seop).
Hyunso or what's the ukes name is ( I clearly forgot ) So the uke was helping what's the problem with the negative energy on the studio because he suspect something that wasn't good. So he tried to figured it out or ask Eunsung whats up with his former teacher and why did he left. So both them help each other or something? Then one of Eunsung's friend bump into them or maybe ask him to meet with Hyunsu about the teacher (?) [I'll be skipping chapter summary] the uke ask his co-worker to gave him a hickey because he want to trick the teacher(?) that thought Eunsung gave him those hickey on uke's neck. So basically he almost rape Hyunso because he put some sleepy drink on his coffee but the uke knows that he was going to do that so he pretend to drink and "accidentally" drop the coffee. Uke kicked him and told him that Eunsung and him have "did it". And the teacher went crazy because he said "Y-You! M-MY EUNSUNG!!" Probably he was obsessed with Eunsung ( Yikes )
Uh also so sorry if it's not still clear! I used Google Len's to translate some of them but i was clearly understand the situation there
I just read the spoilers, the uke actually pretty genius.
