rotfl. i love how ecchi/romance manga always bend the probability in order to have the protagonist get caught with some other girl.
And even though it's never his fault, protagonist always looses his composure and acts like he really did something bad. He starts making ridiculous excuses and they never work. Girlfriend starts running away crying and protagonists tries to chase her...
I'd happily watch ecchi where protagonist calmly responds with "It was her that kissed me - and if you don't believe me, then it's your problem."
