Real life*
totally agree! during that scene it was DEFINITELY more of his over possessiveness rather than his inability to understand emotions...because if we were to use his logic of hyobin is "a grown man he can take care of himself" then him telling euntak to stay and take care of him cause he's sick cancels out cause he's also 'a grown man and should be able to take care of himself'
i'm not dome reading the manhwa but the sickness too looked forced like it was his jealousy that was making him sick rather than an actual cold or headache or something
If my best friend is sick and ask me to come over and bring meds then I would run to him... I know ML has difficulty to understand emotions bla bla but that doesn't justify his behaviour to stop MC to check up on his BFF... It was a huge red flag to me!
Imagine this in real love !!! Eew!
