It was a very hot day today and you were pretty much sweating all over your body, so you decided to take a bath to refreshen.

Though, seems like Haru, your boyfriend, is sweating too so he decides to wash his face. He just went to the closest bathroom— which is the one you're in. He opens the door, tired. He was hearing something before he did but couldn't make it out, (it was your singing) and then it stopped when he opened the door and saw you. naked. Your face flushed red. seems like it wasn't just yours though.
