Beorvy's Questions (2)

I was talking to a friend about bl and we went to the topic of the mc raising the ML
But it reminded me of a short manhwa where the mc loved his best friend and would babysit his son just to be close to him, and let the kid call him mom when no one was around, got off on it once, realized whay hes doing and distanced himself
But years later the kid comes back and asks the mc to be in a relationship with him

I cant remeber the name of it, and can't look for it in my already read list, since it got wiped

I read this bl manhwa like idk, possibly last year or 2 years ago, but I can't remeber the name of it for the life of me and I wanted to reread it ( ｀Д´)/

But the plot of it is an office worker has a crush on his manager and gets a pocket puzzy that magically links to his manager, but he doesn't think it linked to him

I do remember a scene where he's accidentally takes it to work and they see it...but mf goes "oh its a pen case" and shoves pens up his managers ass
