I really admire the in-depth study you did for this chapter. The emotions were very true to the characters and very well written.
So far I notice no grammatical errors either. So pretty good!

Finally had time to read this in peace (work is killing me. And Ame did her magic once more, seriously you never dissapoint me with your writing! Thank you so much for writing this. The anxiety attacks Rika gets at the elevator felt so real for me, poor her T.T I wish the announcement about V route will shed a bit about their past and I'm kinda glad I read this now, it felt like a teaser/intro for that route already hahah xD Stay healthy, Ame~!
