Inderect kiss so much shown in manga, simply cuz authors put their personality and traits in it.
And that means, most of them share love for 'inderect kiss' cliche.
The thing is, most japanese (regardless of gender) is very conservative, shy and timid.
I also heard that in current schools there small amount of couples (if they have any at all), I dont know how much of that actually is true. But looking at them, it is very likely.
I bet, most of authors are single, and live loveless life. Especially male ones.
Damn, sometimes when I think about Japan, it makes me depressed.
