Clannad - Season 2 Episode 3 Hearts Out of Synch

Yohei and Sanae go out on a date, accompanied by Mei, Tomoya and Nagisa. During the date the group witnesses a young girl being bullied by some slightly older boys. The scene is resolved by the girls older brother rushing in to help his sister. Mei remembers how Yohei used to be like that, but once he joined the football club he didn't seem to care about her any more. The group then tries to provoke a brotherly response from Yohei, to get him to stand up for his sister; Tomoya pretends to be romantically interested in Mei, but despite being shocked, Yohei doesn't say anything to oppose them. Mei decides to stay a little while longer, as she can't leave things the way that they are.
