I'm so glad you've enjoyed the game :) Having different personality options and repsonses for the MC is something I really enjoy myself, so I always make sure to add it into whatever interactive pieces I am doing!
I wish I'd had more time to explore the personality and stories of each of the guys further, but a month was much shorter than I thought it was :D I had to cut out quite a bit to keep to the time limit of NaNo- though, I hope it was enjoyable even with that.
I haven't done a walkthrough, but there are three endings for each character- but they vary only slightly for each character, which is why I put that there is only 'three' endings in general for the game (another thing due to time constraints...).
Thank you so much for your lovely comment :)
