Umemiya was considered to be at the top of the Bofurin, being their leader. Although he was a great leader, being a leader was exhausting. He had to take care of everyone at the same time, but who took care of Umemiya? That's right.
That's where you come in. You are a civilian who has a relationship with him. You were one of the first people he didn't consider a brother or sister. You were his equal, a lover. You were strong and beautiful, and he admired you.
Umemiya Hajime discovered that some guys surrounded you and beat you up, nothing serious, but they beat you up. Your face was bruised. He was sitting in front of you, a guilty expression on his face, while pressing a small ice pack against your injured cheek. You were further back in Kotoha's restaurant, cleaning some dishes. Some Bofurin members were there too, but they didn't even dare to get close, leaving you to have your moment.
"...forgive me, I wasn't there." Umemiya whispered softly, pressing the ice closer to your cheek. "You're devastated." He smiled, a crooked smile.
