Considering the song and the fact that you need her to break up with her BF to show that there's more than meets the eye I would say that it def. fits Hannah theme that author went with.
If she was as we first thought easy wild girl we would already score with her meanwhile she didn't even went completely crazy after discovering MC secret for now at least.
Lisa as our MC main crush will also go romantic way no doubt.
NOW KIDS, UNDERLINE IT! IT'S IMPORTANT
Upon the basis that Hannah and Lisa now have quite a few favors on Jane, I, firmly, believe, and even assure, that their sex scenes are going to be an optical feast which the dev cannot be too devoted to present.
The emotional contagion for the two has been placed right, waiting for an eventual sentimental blast of blooming.
I do ADMIT that I'm a bit jealous after seeing Himiko's sweet first time while Lisa, and Hannah still have to wait. Especially for Hannah, being half naked, she's ready for Jane, and she already knows Jane's hidden meaty beast. Yet a damn phone call made everything slow down!
Nonetheless, Lisa now is still not ready for an advancement for porn logic. She's still sticking in an atmosphere of emotional recovery.
Meanwhile, however, I see great potent and ambition, in the eyes of the dev! Maybe these two girls needs a thorough preparation. And I trust him/her
So I can understand the next update might have to take long. Well fair for me. And it is right of the dev to rest a little bit if being quite overwhelmed.
