I'm so so appreciative of anything you're able to do scanlator-san!!! 😭
As a 33 year old woman who also has had to speed run being an adult (Quick timeline: first job/got degree at 27, first kiss/relationship/catastrophic breakup at 28, moved out/got driver's license/engaged at 31, first full time job/married at 33) I feel particularly bad for Nanami.
You can be that far behind, but people's expectations of you will not scale, and the rejection, criticism and shaming can really kill your motivation. If this dude isn't a creep (unlikely), and is super patient, Nanami might actually be able to grow with his support. Not gonna hold my breath though, this is a rather tragic manga lol
