http://www.mangago.zone/read-manga/sakamichi_no_apollon/ is one of my favorite mangas of all time. It has an anime adaptation and a perfect soundtrack too. But it's a manga, not manhwa/webtoon like the ones you mentioned.
omg that's really good i remeber i loved the anime too
Thank you so much!
I don't mind if it is not a webtoon. Thanks for the recommendation, I will definitely check it out!
Hi guys! Can anyone recommend me a manga with deep friendship between boys or father and son or brother and brother relationships with very little romance . I don't want any shounenai or yaoi. I interested in mangas like tower of God, underpin, trump, black haze. Thanks
