I think Xiuhan is the true definition of a bromance, one of those “we love each other and will do practically anything for each other to the point where people would mistake us for a married couple” kinda bromances. The ones that would probably have fights with their girlfriends about in the future because they’re too attached to each other and the girlfriend would end up being jealous. Have you ever seen the show “Boy Meets World”? If not, two of the main characters are these childhood male best friends that are basically inseparable even when they get into serious relationships with girls. That’s how I think Xiuhan is.
