Thanks for mentioning that. I just read it now & LOVED it. I have a non-BL lists which has a few of my most fav age-gap mangas. Take a look around if it helps you in anyway - http://www.mangago.zone/home/mangalist/53203/
I mentioned which ones have age-gap in my reviews. Although they are STRICTLY Older guy-Younger girl age gap.
Oh my....You are a CLAMP fan too? It seems like we have a lot in common when it comes to mangas. Cause thanks to you I have read all the works by Tsumumo Gou! And loved them! So, Thanks again for mentioning that! I also really miss CLAMP. Especially their older works, which are so much better than their recent ones!
I just read manga with shota tag , but it's not as cheap as the other (I'm sorry) called Vocalise by Stukumo Gou, I search on web and havent continued
So I wonder, if everyone have information about this manga or maybe can give recommend manga not only yaoi , but it must be age gap I'll really thankful :)
