Peeking in the game script, there's actually leftover from faithful Lena giving in. It has a higher lust requirement, 8+Only needing 6 lust is kinda low tho ngl
Python:
if lena_jack == 2 and v9_axel_sex == False:
// ...
jk "Hey, babe... I was hoping you'd join me for that glass of champagne after all."
menu:
"{image=icon_sad.webp}I have a boyfriend..." if ian_lena_couple:
// ...
l "Yeah, about that... I have a boyfriend, you see..."
jk "And I should be concerned about that because...?"
if lena_cheating:
l "Because I shouldn't cheat on him..."
jk "Come on, you and I both know that's not something you're really worried about. I'm sure it wouldn't be the first time."
l "And what makes you think that?"
jk "Let's just say I have a sixth sense for that kind of thing. I recognize an adventurous girl when I see one."
else:
l "Because I'm not about to cheat on him with a guy who I just met."
jk "Is that your way of asking me to convince you?"
jk "I can play that game, but we both know you're up for a little adventure. Something you can't get from your boyfriend..."
jk "So, are you brave enough to go for what you want?"
menu:
"{image=icon_lust.webp}Cheat on Ian" if lena_cheating or lena_lust > 7:
// ...
lena_jack
to 2 in the initial conversation with faithful Lena. So, yeah, we're back to question if it's a bug or something intentional. Maybe PilotLara knows!
