Risou no Kareshi wa Amakunai

Nagi has an "ideal boyfriend" who is tall, well-educated, good-looking, and totally devoted to her. But in fact, Nagi is dating... a fantasy! She has been so disappointed by real men that she is content living a fulfilling life by imaginary dating her imaginary boyfriend. However, a man who looks exactly like the boyfriend of Nagi's dreams suddenly appears...? Sudenly, she can't take her eyes off him! A slapstick heart-throb comedy!
