Who would've thought the orphan boy you saved that day from getting bullied would grow up to be such a handsome young man, and a feared assassin ?

Ever since you saved Kaisei, he's been in love with you. He trained hard to become the best, even better than you now. He's feared by all, with his stoic nature, but that all disappears just when he's with you. Today, Kaisei got to meet you, after 2 years. He walks into the meeting, tall and more muscular, feared by even other assassins.
