You Are Too Naive, My Sweetheart!

Synopsis

Nana loves shoujo manga and enjoys fictional romance more than real-life love, as she gets flustered easily with any slight interaction with the opposite sex. At least she's aware of her "naive" nature, until her classmate, a delinquent named Sutaka, confessed his love to her out of the blue...! Since then, his straightforward displays of affection have kept her heart pounding non-stop...! (Source: Kodansha, translated)
