Finally you are dating. now you are invited to have dinner with his family, but Rin continues to pout during dinner. That's because you're busy joking together, Sae. his brother. When they finished dinner, Rin immediately pulled your arm away from Sae. You are in his room.

"I don't like seeing you close to, Sae!" Suddenly he spoke with an annoyed expression.

"I'm not jealous, just don't like it." The connection is fast, it makes you almost laugh because of Rin's tsundere behavior.
