I'm aware that is her character, but that's why the portrayal of the character is inconsistent. She had always wanted romance, but she either chose Alex (who is not romantic) or Max (not romantic either). That's why it's backwards. Instead of starting from romance to build up into something more, it starts from sex acts first and then working on romance.
I don't expect BB to be the perfect game. I'm simply saying that the writing isn't great. Whether there is a porn game that has good writing or not, that's besides the point. (sidenote: yes, there are porn games with good writing)
This is an incredibly over-simplified interpretation of Alice.
1. Max won her over for helping her with her blog? No. The first sober sex act between them was simply her following Kate's command to suck his dick.
2. Alice's true feelings if you give her candies? No. Being drunk and unable to control herself is not equal to true feelings.
3. Spanking dialogue being considered as compliment? Yes, but considering a sentence as compliment doesn't mean that she's interested. You can approach a random girl and say that she's beautiful and she'd thank you for the compliment, but it doesn't suddenly mean that she's interested in you.
This is an example where someone is trying to fit the puzzle by only picking the ones that fit and pretending the ones that don't as if they don't exist.
1. Sharing the room? That's because if she got her own room, that means Ann has to sleep on the couch. Read the dialogue again, she insisted Ann to have her own room as the reason why she doesn't mind sharing room with Max.
2. Going to Max to get help when there's a problem? Isn't that what little sister normally do to the older brother? Plus, there's pretty much no indication in the game about Lisa's relationship with Alice. If they don't really have any relationship, Max was pretty much the only one she has to rely on. Not necessarily "secretly in love with".
3. Lisa got wet very fast? Sure. Why? Because Lisa is a pervert, as simple as that. Her loving sex (or to masturbate) doesn't mean she's in love with Max.
Unfortunately, that is irrelevant to my initial post that you were replying to, that the
writing is not great. If one has to rely on facial feature that would allow people to just interpret it however they want, it only shows that the quality of the writing is not up to par.
Your interpretation is as if a girl is being nice to you then she's interested. That's not how it works. Here's a spoiler for you
