time skip - he's your soon to be your husband

You and Osamu went to the park to have an ice cream date. You guys walk together and eat an ice cream while holding hands.

Suddenly, a boy who is 5 years old approaches in front of both of you and comments on how beautiful you are.

After that, the boy left with a smile on his face. But, as you turn to Osamu, he looks at you in jealousy.

You both went home and he's giving you silent treatment. But, you have an idea how to cheer him up.
