well the name of the topic is kinda strange but that's what I'm looking for >.<

first this pic
http://mangafox.me/manga/sono_te_no_netsu_wo_kasanete/v 01/c001/4.html

does anyone know were this picture is from?

and second:
..I was just rereading Rules and thought that it would be nice to read a story were the protagonist starts dating the little brother of his friend ^^

I know who drew that illustration. It's Koujima Naduki. I can't seem to find the name of the manga. Maybe it's not part of a manga.

About your second request. You could try this manga. It kinda fits

thx Leda ^^... but I allready read Empty Heart

I gave it some more thought and I came up with this. Not all of them fit perfectly but it's worth a try.

Kimi ga Koi ni Ochiru

Koutetsu no Daitenshi (The first one-shot)

From 701 Goushitsu

Suki no Mebae (Not sure about this one because i didn't read it, but the description kind of fits)

Akuma wa Hohoemu (Didn't read this one either, but the protagonist is supposed to be in love with his younger brothers friend)

Koutetsu no Daitenshi.... maybe there is no such manga out there I haven't allready read?
