Kiba: when you leave him, he'll pout with puppy dog eyes until you come back. It gets you every freakin time. How can someone be so hot yet so adorable?!
Neji: he meditates and trains to keep his mind from wandering. When it does it always comes to you. He will sit down an drink some tea while thinking about what he's going to say when you get home.
Sasuke: stares at the ceiling and contemplates his life.
Itachi: he acts like it doesn't matter, but he really misses your warmth. He craves it. When you come back a hug is the first thing you always get.
Deidara: Dei makes sculptures of you. He's never satisfied with them though. Once you come back he always compares the two and finds that the clay version isn't as good as the real one.
Naruto:
1.eats
2.whines
3. RepeatChoji: Choji eats alone just sitting there bored. When you finally come back he'll share his chips with you (but not the last one) and maybe even go on a walk.
Iruka: he grades papers. You always stay later than he does because you help teach extra skill practice after school. When you get backs Iruka is done grading and cuddles up to you on the bed
