I can't quite place my finger on why, but Lena's slut arc doesn't feel as fun as Ashley's from GGGB. Generally I preferred the Good Girl endings from that game, but was still down to explore the Bad Girl endings regularly.
Lena's bad routes feel... mean spirited? Sure Ash had some pretty bleak endings; Eva and Bernard commiting suicide, turning Iris into a sex slave. But there were also some empowering bad endings. Becoming a gang leader, turning into an influencer, and bimbo and BBC routes all felt good. Like at least Ash was happy with those outcomes.
I've not been getting a similar vibe from any of Lena's bad routes so far except on Seymour's route. And I'm not confident that is going to turn out anywhere near well for her. Sure she gets to live lavishly for a time, but I think Charles is there as a warning to dealing with him.
