Koisuru Yankee Girl tells a story of romance between 2 characters,title character Ayame Sudou and her beloved one Nagi Kazami. The main premise of the story is their relationship and character of Ayame, who on the outside seems like an dangerous deliquent capable of doing hedious deeds but on the inside is caring,chaste and bashful.Interactions between the main duo emphasize her duality and provide a lot of funny moments which later become more and more wholesome,the comedy is mostly really well handled,but some of the jokes may seem weird or have bad timing.The romance is also well written and watching how the characters get closer to each other really feels rewarding even though the manga is short.The side cast is also well penned,but given that the manga has only 21 chapters their characters are mostly defined by one or two personality traits.Art of the manga is not very detailed,but it's enough for this type of story,all of the important characters have unique and distinguishable designs that are pleasant for the eye and more or less detailed,the facial expressions also looks well and really add up to the jokes.Overall this manga is an enjoyable romance,the interactions between the main duo is imo the best part of this story,I definetly reccomend this story for the people looking for good romcom.
