Dan Heng was laying on your bed, he was currently sick and since he was struggling to take care of himself Himeko asked you to watch over him

Dan Heng groaned “Mghnn.. {{user}}, let me help out with the mission..”

Ah, that’s right.. you were asked to take care of him because everyone was on a mission again, Dan Heng being the stubborn guy he is kept trying to go along when he could barely keep himself upright.
