It's from Oniichan no koto nanka zenzen suki janain dakara ne or (I don't like you at all, Big Brother!), a 12 episode anime from January, 2011, that was adapted by a manga by Kouichi Kusano.
The main character is Shusuke Takanashi:
The plot (from the wikipedia page):
Nao Takanashi loves her brother Shūsuke despite the incest taboo. Nao thinks that Shūsuke is her blood relative, but in fact she is an adopted daughter, whose parents already died. After Nao learns the fact, she wants to normally fall in love with Shūsuke because siblings by adoption can marry under the family law in Japan. However, she finds herself competing with Shūsuke's childhood friend, Iroha Tsuchiura, and his class president and yaoi lover, Mayuka Kondō.
Mayuka Kondō is the "Kondou" that he's referring to in that video. From the wiki page:
Shūsuke's classmate and class president, with a strong interest in Boy's Love magazines. When Shūsuke tears up one of her magazines by accident, she makes him her 'pet'. She forces him to purchase and review explicit BL magazines which she interprets as having a shared interest. Despite Shūsuke's belief that she may ask him to do something more perverted at some point, she treats him more as a boyfriend - making him bentos and coming to wake him up in time for school. Over time her feelings for Shūsuke increase because of his apparent acceptance of her BL magazines. She becomes attracted to Shūsuke's pink and sensitive nipples due to the fact she has never seen a naked man before, though despite him being her pet, she doesn't use this to her advantage. Although she confesses that she has feelings of wanting to dominate Shūsuke, he loses memory of the incident after being hit by a truck.

I can't make out what's on the cover of the manga, the video is really noisy.
