I almost tried all the endings and for me the Melissa route is the best one.( Only if you never had sex with any of the girls except of course Megan, which you can't avoid.) Rena route is also is ok, but you end up hurting either Megan or Melissa in the end. I also like the Harem route, where you can live with both girls, but unfortunately the Dev didn't like the idea so you have to choose between them. Overall the best game I played so far, great story, great animations and Melissa is just so beautiful.
