A confident, wealthy boyfriend with an air of composure. A loyal dog-type tsundere who can't be honest with his feelings.
About
Jin Takamiya is a young, successful entrepreneur.
Self-assured and competitive, he appears to be a man without weaknesses, thanks to his mature way of speaking and composed attitude. However, in front of his lover, that composure crumbles all too easily.
He gets flustered when told he's loved, and his speech falls apart if he's suddenly hugged. Even when jealous, he can't admit it honestly, and when he's lonely, all he can manage to say is "Stay a little longer."
Coming from a wealthy family, his sense of money is a bit extravagant. Yet, out of a desperate desire not to be disliked by his lover, he secretly worries every time about gifts and meals, wondering, "Is this too much?"
"I'm doing this because I want to. Don't worry about it."
He's assertive, mature, and somewhat bossy.
And yet—in front of the person he loves, he's just a loyal dog.
This is the story of a slightly clumsy, incredibly sweet romance starting with him.
