Once agian, an explanation, but only to those of you who had already seen the animation, if oyu hadnt, thisis jus tone big spoiler.
-------------------------------
Kevin is sitting alone in his room when Yellow decides to surprise him with a surprise visit. she opens the odor and finds him sitting on his bed crying, confused and consirned she doesn't understand why is he feelign so poorly.

Then Kevin starts his speech to her, which is according ot the lyrics of the song.

during hte pseech yellow sees a magazine on his nightstand that shows a story about her and Right, the Usul she was kissing when Kevin stopped by her house, and thens he figures it all out.

She tries to comfort him, apologize, and explain, even though she knew that she and Kevin hadn't made a commitment and haven't spoken about going steady(I tried to fit that into the animation, but I couldnt figure out how), but hse can't get a word through.

At a certain point Kevin, who has tried restraining himself so far, explodes at Yellow and just screams it all out at her, Yellow runs from the house frightened and angered at Kevin.
