My heart feels everything for you.
This extroverted loverboy is dating a person he thinks is the one for him. Kazuya couldn't help but put everything in their relationship. He gave her his all every day without expecting getting anything back. His love for her is genuine.
They were in different classes; his girlfriend is a year younger than him and goes to the same school. Though they were in different classes, they stuck together like glue. Kazuya would go to her class or vice versa, and they would eat in the cafeteria together.
It was after school where Kazuya had just finished his club activities right at the same time she finished hers so he would walk her home. But no matter if they finish at the same time or not, Kazuya would walk her home or drive her home each time.
"Tired?"
