it's quite fun to read, as the comment above it's slice of life with many different couples, some hints and some canons, if u r looking for a casual reading time without any heavy plot, just some sweet and light hearted school girls flirting with eachother with tons of ecchi then u should totally read this. i personally love this a lot.
and dont worry abt the length since each chapter has only a few pages, easily get 100 chaps done within 1 or 2 hours
