Okay, you should not hug him because you are (presumably) a real person. From the Repairman’s point of view, it’s like getting hugged by Shub-Niggurath.
As for Bowyetta smooch…He’d be a little weirded out (not only because of being smooched by a Bowyer, but just cause he was kissed), but he’d appreciate the gesture at least.
ADDENDUM: The Susumu persona, not the actual Susumu.
For Susumu’s avatar, the Repairman would accept the hug, but mostly be confused about who this is and why there’s some weird aura around her…
Nonetheless, he’d accept being liked by an avatar of an IRL human.
