Hi Athrox, there are 3, (routes A/B/C) depending on the route you have taken when you start they eventually start to diverge from Day 26. Also see this post explains it much better on one of mine, a few months ago. https://itch.io/post/10683019

This maybe trodding on possibly spoiler territory here for Soichi's route A, B and C and for future updates but I was thinking that Routes A, B and C should intertwine so it would end up with Yuuichi saying about what he said to Yuuichi on Day 29 on Route C the day after the current update day as finished on Route B's Day 27 and A on Day 38 with a mixture of what happened at the end of route B into C.
This is an absolutely superb game and have been loving it (I saved it before the end of the current part of the game on Day 38), I look forward to see what the future holds with Yuu and Sho's relationship beyond Day 38 until right to the end of their term and to see Shochii's dads face when he and Yuuchi tells him about it plus I can't wait for the next update to be out too.
