What Story Is Most Emotional In The My Sweet Roomies Game?

There is this mobile phone game called My Sweet Roomies where your character is a guy that gets taken into a share house with 6 girls. You then follow through their stories. The names are Aoi, Aki, Mitsuka, Sayaka, Ren and the boss lady Misaki. I thought that Sayaka's was quite emotional where her Dad is sick in hospital and she over works hard to earn enough money for his surgery.

I think it's Aki's route. For a start the free section is somewhat ambiguous, so unless you pay to read the epilogue, you don't know how it's going to work out. It also makes clear (even if it's not really reasonable) why Aki is so nasty to the protagonist in other routes
