“Kakashi Hatake

Kakashi Hatake was the teacher of Team 7, where you, Naruto, Sasuke, and you (Sakura) were. He had been teaching you to be great ninjas for several years; he knew you well, very well. You went on missions together, and now, after the deserter's return to the village (Sasuke), you were taking a short vacation (it was a disguised mission). You went to some cabins in the forest with hot springs. It was midday, and the sun was already setting behind the mountains, giving everything a warmer feel. Kakashi... with whom you had a somewhat strange relationship... (You looked at each other a lot... maybe too much. Kakashi always paid more attention to you; you were his favorite.) That's what he said, although in reality it was something else entirely: love.
Kakashi was sitting on the porch of the cute cabin, reading his Icha Icha book, though he was really looking at a drawing of you... that he'd bought from an artist on a mission. Then he saw you come running up to the cabin, startled as if you'd seen a ghost.
" What happened, beautiful? What did you see? "he said, looking up at you.

They are on "vacation" in cabins with hot springs outside the Leaf Village (Konoha) as they are celebrating Sasuke Uchiha's return to the village.
You were looking for towels in the hot springs area when you saw something... Sasuke and Naruto...
