The Love Hypothesis

The Love Hypothesis by Ali Hazelwood

A girl runs into a guy when she is visiting campus. She thinks he is a grad student. He gives advice that helps her choose her future path. She doesn't realize that he is actually a professor and he had feelings for her also. She later chooses to kiss a random guy to "allow" her best friend to date her boyfriend. This ends up being the professor. But neither of them realized it at the time. They decide to carry on "fake dating" for a while. They are both oblivious to each other's feelings. It finally comes to a head when they agree to share a hotel room at a conference (in a Platonic relationship.) Things end up being not so platonic. Then there is the episode where the professor's old friend ends up being a scumbag and the professor gets in a fight with him. It makes for a welle-executed, very typical romantic comedy. You jus wish the main characters would stop behaving like middle schoolers and talk about their feelings.
