Shinitagari no Kansen Hanzai to Heya ni Furu Nanaji Maz no Ame @COMIC

Yousuke, a university student, lives together with his senior from the same hometown, Tsukiya.
As an infectious disease spreads and everyone is forced to stay home, Yosuke comes up with an idea and ropes Tsukiya into launching a "problem-solving website."
Requests trickle in one by one—the mystery of a withered morning glory, the odd habits of a newlywed husband, the reason a book-loving girlfriend gave up her books—everyday mysteries that they begin to solve.
As they untangle these puzzles, the hidden pasts of the two gradually come to light.

"I wish the world would just end already."

(What can I do to stop you?)

Tsukiya begins to plan the "perfect crime," and Yousuke wants to stop him.
Where will their clashing intentions ultimately lead them?
