That was smooth as fuck, Obito

When Obito realizes that he doesn't have a crush on Rin, he then proceeds to panic because he likes Kakashi instead of her.

First it's denial, second is acceptance, third is buying a book on how to flirt (and pick-up lines).

(Or the story when Obito falls in love with Kakashi, realizes that he's gay and refuses to be subtle about it, Kakashi doesn't know how to respond and other people are left in various states of shock.)
