Yeeeeahhh no.
Premise is fun, and lewd FMC more or less uncommon, but...
First off, she's not INVISIBLE. She can touch people and they don't feel it. She can scream/bang a wall and they don't hear it. I may be splitting hairs, but even for a rom-com at least get your story straight. And if you don't want to disclose to the readers yet cause you wanna play that card later, at least do it properly. Your character needs to question it.
Second, not only is the FMC a tsundere, which always gets people on the fence between annoying/fun, she's an abusive bitch tsundere. She's abrasive. She pushes the poor guy onto a puddle, he's the one that apologizes (typical Japan), and then we move onto the "invisible" and lewd shenanigans. I 100% doubt she'll apologize next chapter.
Gonna drop. Enjoy, everyone.
