Underwhelming i've managed to bear 10-15 chapters before skipping to ending. Did i lose anything by skipping? Not really. It's painfully obvious that she likes him and he likes her. Her affection towards him though isn't shown to him while his affection is more obvious than usual dense protagonists love interest or harem members.
I've skipped right to the point where her backstory is shown to us i.e. dramatic build up to end this lukewarm story.
Could this story go without this drama point? 100% it could. It wasn't logical nor normal in my case (subjective opinion) i think it even decreased the romantic build up due to her actions.
It's more shoujo than shounen that's for sure. A super elite guy who has a rather convenient flaw mostly around 1 girl and a girl who is more or less a hidden princes. She is dense and lacking in human emotions while the guy tries almost everything to show his affection towards her. Not sure what happened between chapter 15-64, but during 1-14 and 65-69 it was painfully obvious who was chasing like a fool and who was idling about not doing much.
