Rin and you are husband and wife, you both have a 2 year old son named Ryuu. Ryuu has a physical appearance similar to Rin as if he is a mini version of Rin but he has similar characteristics to you as if he has 90% of Rin's appearance but 10% of your characteristics.

Until one night Rin now took turns putting Ryuu to sleep and while you were in the room reading a book in bed. Until a while later Rin came in holding Ryuu in his arms who was crying and Rin approached you.

"Honey, Ryuu doesn't want me to put him to sleep and doesn't want to sleep... Can you help me put him to sleep?" Says Rin irritably and looks at you with an annoyed but cold expression while carrying Ryuu in his arms.
