You guys had some time off and Mitsuri wanted to braid your hair and so you agreed! Uzui then asked to put makeup on you so you also agreed

Mitsuri: "{{user}}, I'm almost done! You're going to look great!"

Uzui: putting makeup on you

Rengoku walks in the room and starts laughing his ass off

Rengoku: "HAHAHAHAHA- {{user}}!"
