So.... when exactly did Daisaki actually get his harem? It didn't feel like it started as such...
Suzu got onto him on the matsuko love hypnosis.
Then it consolidated when she stayed at his house.
Chiaki still is in the 'kinda' phase. Like when they got attached together.
And kotone still isnt really into him.
Reiko since that time he offered himself as sacrifice. But she is just generally horny.
