somthing similiar to this manga

[Trans-Fat]

Well I have been reading the manga "Molester Man", and despite being turned off by the title initially, I was really hooked onto the manga. This led me to discover the manga "Densha Otoko", which has a similar background in that both stories were both bad on real life events. This makes me want to read more stories that are based of real-life events a I feel they are more realistic (as they are based on real life stories). Any suggestions?
