✓ - How do they react to praise?
As casually as possible. Typically he accepts praise with a simple thank you, neither declining nor allowing himself to become boastful. Usually, when he receives praise, it’s for his works in city or as a Gym Leader, and given by people he doesn’t know exceptionally well, so it’s easy enough to accept.
Receiving certain kinds of phrase for different things can sometime illicit very different response, and he’s not always comfortable with genuine praise from people he knows well. In the cases where he is uncomfortable, he will often either brush the comment off, respond jokingly with an ‘I know,’ or ignore it altogether.
✕ - How do they handle rejection?
Not as well as he pretends to. Rejection is synonymous with failure for him, which is not something he copes with particularly well. There are only a few things that could illicit feelings of rejection in Volkner, all of which are pretty significant. It’s something he avoids as much as possible, so he hasn’t really had to deal with it since he was much younger... I guess you could say he handles it by avoiding having to face it altogether. Essentially he becomes as perfect as he can.
☺ - Do they prefer sour or sweet treats?
Sweet. He’s not a big fan of sweets, but he does prefer them over sour foods. Actually, he’s a little weak to sour foods, and he especially dislikes sweet and sour combined. He’ll even spit something out if it’s too sour for him.
