I remember reading this one bl manga and one of the main guys had a unrequited crush (obviously lol) on his father/step father or something like that. I think both had a unrequited love/sexuality problems and they became friends because of that. The two men later became a couple
I found it and he had a past crush on his older brother not his father. https://www.mangago.zone/read-manga/bokura_ga_koi_wo_ushinau_riyuu/

I have a personal theory that Claudia and him knew each other and were friends in the past, it's silly I know lol. I just think it'll be sweet for some reason. I also think Polaris knew Claudia too or he probably was just friends with Vincent and working at the Phantomhive manor. I think this because he cares too much about the Phantomhive's so he must have had a close relationship with the past Phantomhives (Claudia and Vincent). The past Phantomhive's were his bosses so why would he be crying about them?! I just don't get it. How close was he to his ex bosses?!
