I think you might like Peach Love and False Memories! Peach Love is a series with an uke who accidentally joins a gang, and attracts the attention of the gang leader. (It's pretty much a love at first sight case). False Memories is a series with a seme whose looks makes everyone think that he's a delinquent, but he's actually really awkward on the inside. The uke in this series is also a delinquent, and the seme's only friend at his new school.
