KINUTA Murako

Yoshida is a young man who aspires to become a university professor. It's the final stretch before he enters the workforce, but there's only one subject he has a problem with: mathematics. He has always abhorred maths, but he will have to face his it if he wants to graduate.

Follows three male models: Maneki Kei, who has a strange tendency to stumble upon dead bodies, mystery nerd Suou Itsuki and flirtatious Touma Simon, as they solve various cases. (from mangaupdates)

The story more thoroughly portrays the three hecklers, Kyotaro, the son of a Shinto priest, Takahito, the son of a priest, and Takumi, the son of a pastor. The days of joy, anger, sorrow, and joy are not as easy as people think they are in a religious organization. The agony of not being able to be popular, and the pressure of being the heir. The pressure of being heirs. Rituals that do not allow for failure. Another depressing day is about to begin! (google translated)
