ITT: Moments in anime where the MC realizes who the love of his life is.
The tennis scene was where everyone else realized they lost, not where Tomoya and Nagisa realized they were in love
Because Haru is retarded, and has been repressing his feelings, it only takes about 10 episodes and 17 years before he realizes he is in love with his sister
>It takes absence to make them realize their love
It's kind of poetic, and the confrontation with Kirino in America was one of the best scenes in the series.
