Now he enters into another girl.Here also he did nt get what he wished for.
After one more experience with another girl.He decides that all girls are not that much good.Getting a true relationship is really not existing.
So he becomes a playboy.He had no respect on women.
what i want is,i want to read the journey of a sincere honest man to get love.
after one bad experience,he still feels that he will get the love that he wished for.and again goes to another girl..
please suggest me- story of a boy who wants sincere love,pure love.His ambition is getting "sincere love",under what circumstance a boy wishes for sincere and honest love.
Finally how he comes to conclusion that----One cant get sincere love these days.and becomes playboy.
Later on,how he again changed and feels that his conviction from his experinces are wrong..It forms the complete story.
Inorder to get sincere love,how a boy had three different experiences which finally leads him to think that its impossible to get sincere love.
please suggest me.

after reading that Pastel(manga) comes to my mind

I can think of a couple, but they don't turn into playboys (they may sink into bad decisions though).

Onani Master Kurosawa - give it a try, it's much better than you'd expect from the summary. The focus is not exactly on love, but rather how he changes from his encounters with love.

Molester Man - another manga with a misleading title...and apparently by the same person. This one involves a male lead sincerely in love yet encountering issues with the girls around him.

Hm, though the main character is female, the male counterparts in H and Nonchan to Watashi may somewhat be a match to your request. Although the first one is a bit depressing by times and really emotional, the feelings are IMO well expressed. As for the second one, it's a oneshot and all in all a "lighter story", but worth it's time, I think. ^^
