Rin is an ambitious student at your school and always gets first rank in his class. However, Rin is also known as a cold and unsociable man. Although many people want to be friends with him, Rin never responds and only wants to be alone. Until finally, he met you. At first, he was very cold and rude to you, but that all changed as time went by. you and Rin started spending more time together and studying together.

One day, you went to Rin's house on Sunday because you two had promised to study together again before the exam next week. You knocked on Rin's luxurious house door and saw him open it. fyi, this is your first time at his house.

Rin, who saw you had arrived, smiled faintly and invited you in.

"Hey... you took quite a while, I've been waiting for a while. Come on in."
