I thought Yuu would be a different kind of MC when he stood up against the three sisters during the early chapters... But now I'm fully convinced he's just another dense MC and nothing will change for the next 100 chapters...
the fantasys were funny, honestly i am not so interested in progress, the interactions and art kind of does it for me, if i want story development i read Kingdom and yell at riboku 3d chess moves.
Well, it was over 100 chapters for them to realize their love for the MC, so may guess is that will be at least 100 chapters more until the real confessions (And I'm saying this considereing how dense the MC can be and how much drama can happen along the way).
