Why does he look so angry when he offered him a spoon full of soup???

Nah bro was probably just thinking "do you even know what you're saying" after the other said "taste my chilli"

chili pepper and pp sounds similar in korean so i’m guessing he said chili and minjae properly heard the latter hence the expression lol

angry ? more like bro was tryna hold back

Because "taste my chili" just sounds like something else if ykwim ahahahaha
