I just read through the entire thing up until this point. Chapter one was rough. I mean, you chase him off the train when he leaves and as he tells you to leave him alone you assault him (by kicking him in the nuts). Was that supposed to be funny because it really wasn't.
Then this last chapter you break into his place by force, will probably beat the shit out of him for doing his business in his OWN place, then will call him a pervert when the girl is trying to 'catch a ride'. Yup. Sounds about right for what MAY happen next.
Also, not to mention that you are the clear source of his phobia and that you also seem to have a thing for him (maybe you just want to make it up to him and can't find the right way). Of course, you will also probably take some moral high-ground and be judgemental about his relationship with this woman.
All that being said, I'm in it for the Plot and Story. That sex doll sure has a lot of Plot and Story ... plus she thirsty AF. Now if the MC would stop being such a pussy beta and/or pansy we could go somewhere with this.
