I only watch the first 2 episodes of this particular anime before I forgot about it due to work and that anime about a guy (high schooler maybe) where I only able to recall his friend where he looks like an adult man but he's high schooler due to his big built body. He has a very thin mustache and dyed his hair blond. I think the other friend tries to convince him to go back to school and they succeeded. it might be released in 2021-2023. and now I have a plenty of time to watch it in one go. Can anon help me what's the title?
