If you want to perhaps have, a subjectively, better set of pairings and outcomes.
Ian / Allison
Lena / Holly
Perry / Emma or Cherry
Cindy / Wade
Louise / Jeremy
Stan by himself (for now), but Lena is decent to him and tells Louise to grow up and pay rent.
Ivy (likely by herself), but Lena doesn't fall prey to Ivy's more negative influences (drugs, smoking, Stalkfap, etc.)
Axel / Cherry with Lena having accepted that part of her past but having moved on. Willing to hear Axel out, but firm in not indulging him further.
Lena doesn't cheat with Mike, but agrees to collaborate with him on music. Leaving him with his girlfriend (may or may not be Gillian)
Robert crying in the side closet at the restaurant, because he's a creep and nobody loves him.
