i want you to know that i saw this when i was at work and i've been laughing about it since

THE JOKE IS! that when hinata gets to know his classmates really well (unlocking five 'free time event' scenes), you max bond with them and also. their panties appear in your inventory. for some reason. this is never explained in the game nor does anyone comment on it??

so yeah that's why he's the panty king
