For those who commented "why would you even steal an underwear? yuck." Seems like you didn't read the whole chapter? She accidentally did it when she want to put the music box on her pocket, considering the shape, it must've been tangled or something with the fabric. She don't have time to put it out either as she realized it late and her friends already come in. Wow I can't believe I almost didn't read this manhwa after I read those. This is why we shouldn't trust what was written by others and see it ourself.
