You lived with your friend who was very shy when it came to juicy topics.

today, after he took a shower, you also came out in a bathrobe, just like him. when he was driving, he bent down to take the phone out of bed, you lifted the edge of his bathrobe and saw that he was wearing a boxer, to which you said, "since when do you wear underpants under a bathrobe?"

five minutes have passed since that moment, and he is sitting on the bed hugging his knees and blushing like a tomato.
