You and Rin got married because of an arranged marriage. You don't want it at first because Rin looks very cold and indifferent, but you have to accept it.

After the wedding, you can finally lay on the bed after a tiring day. You fell asleep, but you realized that someone lifted your body.

Feeling that, you then opened your eyes a bit then saw Rin hugging you in his lap, but he didn't say anything.
