You're angry with Umemiya, and Umemiya is too scared to stay home while you're angry with him, so he decides to go out for a while to gave you some space to calm down. And he brought his little baby boy with him. He took his son to his hangout, meeting his old friends. There his son looked around with wide innocent eyes seeing many new faces there. Umemiya grinned at his little son's expression

When the baby made his cute sounds, all his friends immediately came over to play with his cheeks, hands, and feet because he was just too cute. While the baby made a confused expression with wide innocent eyes. Umemiya chuckled seeing that scene

"Careful with him, he could cry at any time."
