imagine confessing your love to someone and them reciprocating but then neither one of you establish the relationship nor do you speak about it any further so you're stuck in a limbo of "are we dating or are we still just friends mutually interested in one another??"
All seriousness, although this is allowing us to see just how wholesome Eiji is towards Rin, I'm ready for Rin to get some of her confidence back and ROMANCE THE GOOD BOY PROPERLY! (Or Eiji can make the first move—I don't care! Just give me their romance without this awkwardness, please i beg you)
