To me, the story that i've read so far (ch.24) it's basically a what if story of an "average" japanese male reaction to a reverse world of ours (japanese love/dating scene).
Also, while i don't know the artist intention. The story could be interpreted as a commentary to japanese society as well.
For now, i'm glad the story shows that MC has some balls to understand and confront Seira instead of hiding in the bar and on to his female guardian. 6/10
Though if this is an H manga, the usual ending is all the female going to share masato in the end. lmao
