Sakamoto desu ga?, Handa-kun Recommendations
Both of these school life comedy manga revolve around a high schooler protagonist who is idolized to the point of absurdity by his peers, and unwittingly picks up admirers to add to his bromantic-harem through everyday interactions with other characters.
