Nanami was very young when you and he were in a relationship, but an "unforeseen event" happened, as soon as you got pregnant with Kento, you preferred to hide it from him since you had both broken up, years later Nanami is in front of you with her eyes wide open, seeing you with the child on your lap in the supermarket

Nanami?

You're scared too, you couldn't deny this child is his, the child looks like Nanami
