They're eighteen here.
I'd like to take some time to say how I love these two's friendship. As much as I love Hotaru and Mikan's.
They care so much for each other, it makes me cry (crybaby). Natsume is okay with everything Ruka wants 'as long as he's happy.' And Ruka would not let Natsume sink into darkness alone. They understand each other. the things Natsume does that would make you think he's mean and bad, Ruka can see a deeper motive, or concern.
It's a really beautiful friendship. And you don't see them fight or argue about Mikan, do you?
Hmmm... I think Ruka's better-looking than Natsume. Natsume just has the attitude.xD
Pen & Ink
PS. If you read the manga School Rumble
you'll know where I got these poses for them. Natsume has Imadori's pose and Ruka has Asou's. The poses were just like them that I had to draw!
PS2. Ruka looks more like Sakurano Shuichi, don't you think?
PS3. Natsume has two alice stones. Why? One is Mikan's and the other is a healing stone Kaoru got from Yuka.
