Just read until the chapter 15, at this moment I feel the three girls just annoying, the mc is just plain and don't even try to make a point, just flow with the current and that's it. The most annoying momment
The chapter where two of the girls interrup the date with the mc.
Oh no, poor MC, how will he ever deal with having girls that blindly love him..... At least this series is trying to give the girls some characterization instead of just filling in the archetype bingo.
It's quite easy to introduce Iinazuke Kyoutei: a generic ecchi. Pretty girls come out of nowhere in love with the MC, a gay who shows no interest in any of them (or a personality).
Poor even for those who like ecchi, but it is not unpleasant at all:
Story: 3/10
It's mediocre and made just as a pretext for sensual scenes, just a little better than hentai scripts. The worst point of this manga. Things are just too convenient for the MC and happen for no reason.
