The story is great and original with what it raises but I only have a slight personal complaint and it is the subject of hearts, I mean I understand that it is to mark which option are to flirt or take you to the romantic route but personally I feel that those types of dialogues/options are better when it is oneself who must think what to say or what option is correct and not follow the already established path, it is just an observation but apart from that thorn I am anxious for chapter 4
I'm not sure what you mean? There is NO established path. The hearts strictly denote what responses are flirty/romantic and which aren't. They're tone markers, nothing more; they don't lock you into any route.
You can pick whatever dialogue option you want. Furthermore, you can pick absolutely no heart options and still choose a romance route when that choice eventually arises.
