I found an ecchi title that might interest classified it's called koe de oshigoto.even though the protaganist is a female it kinda reminds me like kiss x sis where they try to show everything but they don't. there are hints that there could be romance maybe in the manga version.
there's a manga I want classified to also try but I don"t think he will take it seriously if he reads the title or synopsis. When you start reading this you will notice that the main protaganist is very similar to light(deathnote) but is the exact opposite of him so you will see him deal similar issues as those in welcome to nhk. whoever read this this manga or whoever has time to read and finish it to convince him to try it out but
DON'T SPOIL ANYTHING
I just want him to look past the title and synopsis
here it is
