I'd have preferred it if Nakota ended up with Shimizu. Tachio straight up got a gf for a while and then told Nakota "I thought you were always mine". What? Does he even know how relationships work? That's beyond selfish. He had no right to get jealous and dictate who Nakota can date. I really hate this ending.
His childhood friend is very toxic. We're all hoping he ends up with his sunbae but by yaoi standards it won't happen smh
