Miniamaru Kareshi (My Overly Attached Boyfriend) by Mizuki Hoshino, Volumes 1-13 Margaret Comics This is a romantic comedy about Iroha, a high school girl with no experience in love, and Kusakabe-kun, a love expert with a gentle appearance but an overwhelming amount of love. The story depicts their relationship as they navigate unexpected thrills like kisses and holding hands, and are tossed around by his excessive affection. I've only read it once, so it's in good condition.
