It's an interesting bait and switch methodology for getting your childhood crush to fall in love with you. Overall the manga so far seems like it's trying to do ALOT at once, part NTR (but not exactly...), part sweet, part ecchi all at once. There's a possibility this will all come together in a wonderful way but, that's yet to be seen. A major gripe is that the main love interest doesn't exactly react as one would typically expect. It could be there's a yet to be determined storytelling reason for this but, it's an aspect that pulls one out. The main protaganist however, isexactly as one would expect for a more tomboyish gal.

The characters are cute and the art and expressions are lovely, so if nothing else it's an enjoyable read for that aspect!
