I will just say

I'm thinking Bf's company had a thing with "sponsors" (the company forcing their talents to sleep with potential sponsors/clients) to which bf likely endured and didn't want Shin to go through - but hopefully I'm wrong（/TДT)/

It's been a while since I read this ╥﹏╥

Ugh I hope that’s not the case, the sponsor thing

The thing is that Shige never wanted to be in showbiz but he was photographed kissing Shin when they were in college and the CEO blackmailed Shige to sign with his agency and didn’t have a say in any job he took and had to play a role of a prince he hated. Also the one who took a picture is Shige’s manager, who also feels awful but couldn’t refuse because of the CEO. At that point of the story the CEO is still blackmailing Shige to do what he wants or he will release the picture… ┗( T﹏T )┛

No, that's just pretty much every show biz manhwa's plot. And even then it almost exclusively happens to bottoms. He was "just" blackmailed into becoming an actor

When Shin started becoming bigger Shige wanted to quit showbiz since he didn't want their time together to be curtailed by the demands of both if them being famous. He was happy being a normal person who could be with Shin without.creating problems because.nobody would recognize him or know of him. The CEO didn't want to lose the money Shige brought so he had his manager take the pic of him and Shin together and then blackmailed Shige to stay otherwise he would use the pic to end Shin's career (not Shige's, since he himself doesn't care much). Shige doesn't want Shin to find out because he thinks that if he knows Shige is being forced and blackmailed because of him, Shin will quit showbiz for good in order to remove the CEO's leverage and free Shige. Which tbh, its pretty reasonable assumption.

What pic of him and Shin together?

Oh my gosh, thank you for recapping, you just jogged my memory like unclogging a toliet. Gosh, so much stress, I hope it gets resolved well... Whenever we get the next update - if soon, or at all

(my last comment applies to you as well my good sir. Thank you for sharing ╥﹏╥, glad to remember the storyline again - really didn't want to reread and give myself a heartburn)
