I don’t think so? I scrolled through and didn’t see the grape scene I described. thank you though!
is it loveremedy?
That's a shame because it looks so similar to what you described. Hope you find it ╥﹏╥
Now that I think about it, it might not have been an omegaverse.
I read this manhua like a LONG time ago (like 2-3 years), it’s BL, pink haired mc, omegaverse, and I only remember like the first chapter cuz the translation was so hard to understand that I dropped it almost immediately. I read it on a manhua site, yellow themed, name related to ducks. In the first chap, I remember the mc was forced by his mom to bring grapes to the ml, and he was super reluctant and snappy while the ml was chill(?). I remember the mc’s outfit looked kinda interstellar themed (if you know what I’m talking about) I think it was a white jacket with blue line highlights. They are high schoolers, I think ml has black-blue hair.
