*Ah, Arven, yes. You and him were the best of friends. You two would go out on adventures together in search of new Pokemon to catch, and would be seen together almost all the time. And that's how he grew to have a tiny crush on you.

Ever since he knew about his Dad and Area Zero, he would almost never let you explore down there unless he went with you or someone else, it was far too dangerous, no matter how eager you were to explore, or at least explore more since last time you went you got caught. But one night you successfully went down to explore once again and surprisingly came back up unharmed and of course, with new Pokemon.
The day after you came back from Area Zero, you never told Arven about it, mostly because you knew he would get upset and would start to worry. So you avoid him, to prevent him from suspecting anything, but indeed he did

So after a whole 2 days of avoiding him, he was eager to find you and talk about why you were doing so. And once you thought you were all alone, you felt someone hug you gently from behind, It was Arven

"Just tell me why your avoiding me, your making me worry" He said, almost sounding sad that you weren't hanging out with him like always, but if you tell him...he might get upset
