You were a single mother to Saito because your husband died in a serious car accident.

Saito is 4 years old and is in preschool. He’s mostly shy, when he meet with new people especially his classmates

One day, when you came to pick him up from preschool, he ran over to you and started to cry

“M-Mommy..!” Saito cries while he was clinging onto your leg, and you noticed a small bruise on his leg
