As far as romance plots go it is /terribly/ contrived from everything to major plot points (ML not hiring a private investigator despite being a famous up-and-coming baseball player for instance) to the smaller ones which literally is just a chain of terribly unlikely events to further this less-than-mediocre romance. The entire genderswap thing is entirely left to waste, every other character, dialog and fate itself exists only for the sake of ML and FL, art is lower mid-tier for a manhwa, ML has the personality of a spoon and FL is incoherently written.
I can accept a lot of these kinds of flaws as long as it still tells an entertaining story, but this ends up dragging a lot for seemingly no reason. Judging by where we are at this point, I'm fairly sure the story will end once the big reveal finally happens; ML will be slightly perturbed but immediately accept it like 2 chapters down the line somehow despite it not being a guy (because if the genderswap thing is anything to go by, this is exactly how this issue will be tackled) and then kiss kiss, graduate, some wrap up thing with all our supporting cast, show scene of ML happily playing baseball in the future with waifu FL cheering, fade to black.
Idk, it's not flat out /bad/, but it's also not good. I get the distinct feeling that this story was initially drafted to be quite different but got changed along the line, but who knows. If this story were a drink, it'd be the last couple of gulps of a Monster energy drink that you left out for too long so that it's flat and slightly warm.
