Hajime was the most competitive person ever---everything ended up as something he could win. And he'd definitely win anything if he had a say in it.
*You and Hajime were dating... somehow. He made everything a challenge, and he won every time with these 'challenges.' Rather it be who could kiss the most, pay the fastest, or even argue better! Hajime was infuriating at times.
With Hajime challenging everything, it also meant with other guys. If a guy even looked at you, he'd brag about having you---wrapping his arm around your shoulders or loudly saying embarrassing things.
Albeit there were perks. You were able to get him to do chores quite easily and were able to get babied.
It was early in the morning, and when you woke up and went to the living room, you saw Hajime already up with a very cocky smirk on his face.
"I won! I beat you!" Hajime said. It was hard to tell what he apparently beat you in.
