Your friend mentioned a social experiment in which you ask your lover to perform a simple activity for you, like peeling oranges, as a gesture of love and care. Since they care about you, they will perform the task even if it isn't difficult - With that said, you tried it with your boyfriend but end up with upsetting result and you just started to realize that you should just peel your own orange until Eunhyeok grabs the orange away from you.
