Mostly no, but only after the cutoff.
Prior to the cutoff, the MC still has the chance to kiss Sage at the DIK party (instead of going home to Maya), or to kiss her after he gets proof Chad is cheating on her. The sparring session is automatic, and he can choose to teach her to play the guitar. During the first teaching session, the MC has the opportunity to make a move on Sage, resulting in a led scene if he does so.
The cutoff is during the second teaching session. That one takes place right after Chad asks to help get him back in the jocks, where the MC plays the guitar for her. She hugs him and asks if the MC is only interested in teaching her.
If the MC says it was purely about teaching her, Sage kicks him out and they never become fuck buddies. The MC has rejected Sage. So no lewd scenes, no chance to stay with Sage in Episode 4, no movie night, and no more guitar lessons (thus far).
If the MC says it was an excuse to get close to her (and this will happen automatically if the MC fooled around with Sage in the first session), then he is on the Sage path. He has the option to stay with Sage in Episode 4, he will attend the HOT movie night (even if he stays elsewhere), he will have sex with Sage on Tybalt's bed, and he will kiss her at the end of Episode 5.
