Not sure why people are downvoting you instead of explaining. There's a 'bad' path if Yuu pushes Shoichi too much, and it causes Shoichi to lose control and do something that scares Yuu. The bad path continues from there, there are guides on how to get there on WB's page if you go back a few updates.

In the good path yuu helps him reconnect with his mom (and proceed to do a multitude of things behind his back without his consent but that's a topic for a different time).
