HA I was just talking to a friend about this so it's funny you should ask!!

it's obviously left a little bit ambiguous on purpose, and jake assumes that one of heeseung's friends has said something along the lines of "heeseungie, give me a bite of your ramyeon~" as a joke (I assume we have all made the joke before of asking a friend to share food while not physically with that friend)

however, what was actually said was something closer to "whoa, heeseung, your omega is bringing you food? can you share him with us too?" still as a joke, but a joke that heeseung was less fond of (it was probably said by limji, who is like. one of two people heeseung ever feels genuinely threatened by lol)
