Great story so far, I just hope Yua doesn't get together with Alto (which is most likely going to happen). Harem route aside I've always had a soft spot for childhood friend type romances, and for MC to mostly likely come back and just make her fall in love again and NTR Alto. I feel an AOT ending is come for the beginning of ch4(which isn't a bad thing per say but anyone who finished AOT knows that the story ended while this story is continuing). Side note even after the fireworks why didn't she just confess I feel like a lot of the choices you can make show a clear sign a romantic interest.
