Seriously I have hard time to even recall my top 10 manga!

hehehe thx. But I didn't only rely on memory as I'm also bad with manga titles, i have an otaku tag which i checked and just remembered whether it was a seme otaku or not. Afterwards I did write 'seme otaku' in the tag search and some with one story that i remember reading appeared so i included

Yeah i guess I'm just a noob,in regarding with these types of things...
