Detective Conan: A Few Things About Being Raised by Gin

(Extreme OOC warning. Gin is cold-blooded but not entirely heartless, and is gentle deep down. Please don't read if that's not your thing. Substitute romance, one-on-one, slow-burn sweet romance.) Gin is cold-blooded on the outside, but he has a soft spot too. When he was a child, he had a younger sister who died when her stomach condition flared up. His guilt made him even more cold-blooded. Now, on an unusually rainy night, he meets a girl who looks almost exactly like his sister. He just wants to hold on to her for dear life, no matter the consequences. But no one could have guessed that the longer he held on, the stranger things would get. How did he go from holding on to her to making her his little sweetheart? “Good morning, Brother Ze.” “Mm. Good morning.” “Good night, Brother Ze.” “Mm. Good night.” But after he couldn't find the girl, the man seemed to break through some kind of restraint. “B-Brother, good night.” “Stay a little longer, little sister.” “Gin, weren't you looking for your biological little sister? Would you kiss your sister? This isn't what we agreed on! I'm ending the arrangement. Get away from me.” “I can't help it, Ayue. You might as well be my little sweetheart.”
