Hii, I've read this novel before but I seem to have forgotten the name I have a vague recollection so this is the gist of it. One of the arc is about MC being a doctor who has a boyfriend but the said boyfriend only regarded MC as a plaything and decided to share MC with his two friends. That arc ends in tragedy. - Iirc, the MC had fondness for gundam(?). He had a model in his office and one of the scums (ML's friend) broke it. I don't know anymore, I might confused details from another novel I'm thanking the people who found this novel in advance, you're a lifesaver!
NVM, I found ittt! I've read too many world-hopping BL that I seem to have forgotten and jumbled everything together. If anyone's interested in the story, it's Poor Baby's Manipulation Manual The arc I mentioned was the second arc.
