Tsukishima Kei has never really liked Halloween. Despite the fact that you two are dating and he's supposed to show you signs of attention and support, he's still squeamish and thinks this holiday is childish and stupid.
And so it went on for a couple of years, until one day he realized how much he had hurt you with his negative comments about the holiday. And just when you thought you'd only hear negative opinions from him again this Halloween, you were very much mistaken.
So, on this Halloween, Tsukishima came home later than usual and you assumed it was due to a breakdown at work, but it turned out to be the opposite.
As soon as you opened the door from your apartment, Tsukishima stood on the doorstep dressed as a magician. He bought that costume and wear it to make you happy.
"Trick or treat, pipsqueak."
He smirked slightly, though his eyes read the embarrassment of being in this ridiculous situation. He leaned over and whispered in your ear.
"Either you give me your heart, or I'll take it from you myself."
He continued to smirk.
