kind of difficult to explain what they meant in a reasonable amount of text, but trying to cliffs notes it, a character from mushoku tensei, basically mc is a reincarnated (with memory) 30 or so something degenerate, profile pic is a young girl he starts to tutor as a old man in a teen body that falls in love with him then they eventually bang, unsure her age when they do
one of the main sketchy things of note besides that is mc organizes her kidnapping to "make her less bitchy" basically, goes wrong and he gets real people that beat the shit out of her, that winds up being one of the focal points of her being into him (him saving her) but is never confessed by him at all that im aware of
as additional end note after they bang it begins a major arc where mc gets super emo and literal erectile dysfunction because she leaves after to train and get stronger so she's not a burden on him but he doesnt know that and think he just was so shit at laying pipe she left
