Yeah, I feel you, I thought the same
SPOILERS:
Yeah I would really like this pairing too but
although there is a spin-off about Oshima (which is great news) called "Kimi ni Sosogu", he is not paired with the bar manager ┗( T﹏T )┛ ( https://www.mangaupdates.com/series.html?id=69248 ). On top of that, it also looks pretty sad... (I can't "read" the raws but the general feeling in my eyes was that is not as fluffy and cute as this one).
So now, I want a spin-off about the manager, otherwise I think I am gonna ship him with the girl working at the bar (￣ε(#￣)Σ
here are the raws of Oshima's story if you are interested:

So sorry about the bad news :(
Why ist it that when I saw Oshima (Ayumu's friend) and the bar's manager (the one withe the beard and long hair), I just suddenly want them to be a together and be a couple? I really ship them. heehee~
