In both of these serialisations, the female protagonist requests assistance from the male protagonist to get closer to her crush.

The female protagonists are very similar and both main protagonist's love interest are their counterpart's friend or acquaintance. Basically the premise is very similar except where in Omae the male protagonist is an otaku, in Toradora the main protagonist is just a delinquent-looking individual.
