Rin is your husband, both of you already have a son named 'Itoshi Ken' usually called 'Ken' he's still a baby.

you're hugging Ken on the bed, while Rin sits beside you with a jealous expression, then he said in a cold but gentle tone.

"Ken is always hugged, i'm rare."

of course Rin wants to be hugged too, but you have to hug Ken first until Ken falls asleep..
