Because somebody who has been alone for their entire life (at 30) probably isn't just nervous. Particularly with the crying and leaving with touch, that's probably a deeper issue even just from the solitude alone. And if he misses love it wasn't requited, mentioned at the beginning with khv (no hug/hand-holding).

But yeah, OOP is probably better off than me and I'm projecting. Not saying anything about perfection, just that a random meetup/fix-up is odd and OOP probably needs a little therapy and/or some other form of help, and I'm guessing based on their own words that they know that (easier said than done).
