A lot of good points were discussed and brought up. As I see
lucadiadis went with the "some options you didn't pick" changes the narrative of the story. That is true with her cigarette and drug acceptance/refusal with Ivy. All options are not going to alter the narrative of the story. Some will go hand in hand and hence are canon. Lena's footjob skill is canon, she had a fling with a professor who made her do things and she got good at it. Now you get the option for TMI or stop it then and there. Regarding her threesome with Cherry, it is again a canon. We get the option to make Lena open up to us about her previous relationship. I understand that you don't want Lena in those scenarios but being in denial will not help it. Lena is sexually very open and curious hence she has a BI path. We as a player mold her curiousness and make her act on it. Like flirting with Mike even if she knows that he has a GF, teasing Ian at the record store with his hypothetical GF, BBC so on and so forth.
When it comes to Lena as a person, she never had it easy. Growing up in a dysfunctional home tends to take a toll mentally. She has an abandonment issue which cropped up when her own father left her. She is looking for support that would treat her well and take care of her. We can see in her monologues and even her talks with Holly during her 3rd songwriting, that she yearns for it. During her date with Ian where she complimented a fit Ian, she clearly expressed her thankfulness for taking care of her and treating her right. At the end of CH11 at Ian's place, there is a line where Lena says "I had given myself to him, and in return, he had surrendered a part of him to me that belonged to me and only me". She goes all in in a relationship if she's given time.
Don't get me started on that piece of period blood named Axel. As I said in a previous post, he is very skilful with manipulation and gaslighting his partners. Lena was not in a good place in her life when she met Axel. He played his cards right and showed Lena that he could be the support that she needed all her life. As Lena said the relationship was alright when it started but it soon went down south when that creep's ulterior motive was coming onto the surface. "Axel likes to be liked" The self-entitlement and narcissism are through the roof when you are only surrounded by yes-men who stroke your ego to the fullest. Axel is a 'player' foremost, he is just like Jeremy without being a one-pump chump and much more tactful around girls. He manipulated Lena's feelings and told her he loved her. For Lena, it meant real love but for Axel, it meant he loved his toy. She surrendered herself to Axel because she trusted him. The dom shit that Axel went through with her was just to mark his property. Hence he was in a psycho mode when Lena left him, he got angry that he was not able to make her fully subservient to him. Not being liked by her made him unstable, he finally got a nay-sayer amongst the sea of yes-men.
Lena can act like Axel if she is in a dominant relationship with Louise. We can clearly see what Axel felt when he treated Lena the same way. Louise surrendered herself to Lena but for Lena, it didn't mean anything. It was just for fun. She even said it during the second music gig at the Fortress.
