i really liked this. school life touhou and marisa x remiu are some of my favorite things, so i loved reading this. i love on how popricatio portrays reimu and marisa as well, reimu being fairly cold and marisa being an emotion crybaby. it really makes their chemistry work well.
in terms of the ending, poprication did say that this was the tightest deadline that they ever had and wanted to write a lot, so the rushed ending makes sense.i did wish it had one extra page of flirting or reimu realizing it was love though, just so its solid and not just a thought.
