No don't do that actually. Kissing someone in their sleep isn't quirky or cute, it's bad and I hope the next chapters won't frame it as something positive or brave.
You're in the wrong site for that, pal. Most of us here aren't so close-minded and lacking in willing suspension of disbelief that we'd insist on shoving every minutia of real-life morality unto fanart and comics that are clearly supposed to taken as escapistly wholesome.
I'd actually argue that it's not a problem for people to feel the way you quoted (and comment saying they feel X way)... I only think it's a problem if one uses that feeling to grief on others, i.e. the 1000 comments of "how dare you like this work that I find morally questionable!!" elsewhere on this site
Some people just don't have fiction and irl morality as clearly separated in their own heads as others, and again, so long as we're not hating on each other I don't think that's necessarily a problem...
Personally I was a bit concerned about the kiss but was like "SHE DID IT" nonetheless
