I don't know, the teasing of Elysia and the stoic Kevin just makes a great couple. and their tragic relationship ending is just too good. I feel wrong shipping them.
You're not the only one, after the last chapter story when elysia gave kevin the crystal flower + the converstaion they had just made me ship them definitely
It's always been my headcanon that Elysia was in love with Kevin; but Elysia, being who she is, would never do anything to jeopardize any of her relationships so she quite literally took it with her to her grave.
Well Kevin was really popular in his youth. Most girls want to date him but he's only interested in MEI. He only started becoming an ice block after his MANTIS surgery.
