It is about an anti-bully high school boy who goes on a website to talk to his online girlfriend. When he talks to her, he completely changes his personality and becomes completely sweet. The two decide to meet up in real life. There and then, they find out that they are in the same class, and that they do not get along at all unless they communicate through text messages, so they are in a cafe looking extremely angry towards each other, but talking very sweet through their phones.
The manga follows the two as they begin dating and the progress of their relationship. The manga also follows another couple where the guy accidentally buy a date from another (I think it was a middle school) girl instead of his dream girl.
I have been trying to find this manga for a while now. Any help would be appreciated.
