There are more chapters out on the Korean site, maybe 8? now in English so I could be wrong, but the plot seems to be centered around 3 MC's. There is the actor/model who is is a fan of (lets call him Actor hyung 1), he gets an opportunity to star with him in a film where they will be a couple. The plot to the film is super cheesy, just typical yaoi nonsense. However this is contrasted with the "real life" couple of Actor hyung 1 and Actor hyung 2. Actor hyung 2 is quite possessive, and he has a sponsor, which basically means he sells himself in order to get work on the orders of his agency. He goes back and forth to his sponsor but has been in a relationship with Actor hyung 1 for years, although 1's manager has reservations about this as 2 is quite controlling over what roles he thinks 1 should do. Anyway, actor/model ends up in a hotel when they are shooting their scenes off location. Actor hyung 1 gets drunk and then says he will give his no 1 fan a private show or something cringey like that. They sleep together, and Actor hyung 1 wakes up the next day hungover, by his manager who is annoyed at him. That's all I can remember from the raw chapters so it's quite a poor description.
Hi, is "Behind the scenes" (from le.zh.in) on here, maybe going by a different name? Thanks in advance :)
