Would you mind doing headcanons for how Richter reacts with receiving all of his s/o’s attention? Like he notices he doesn’t have to fight for her attention or affection? ( If requests are closed, please ignore it!)

Admin Mawile: (ゝω･)ﾉ

-Not having to struggle for any kind of acknowledgement under his brother’s shadow is an entirely new feeling for Richter, and it takes quite a while for him to really believe that you want only him. He’s used to being used and overlooked, having to force his way to people’s good graces, and having all the attention he could want with no cost comes as quite the shock.

-However, all the attention goes to his ego almost worryingly fast. Richter can be painfully proud, and having someone treat him like he’s worth everything to them is a good way of inflating his sense of pride even further. In a weird version of a superiority complex, having even your attention convinced him that he’s worth more than his brother ever was, all because one person loves him with everything they have. 

-On a fluffier note, you may actually catch him off guard by being willing to give all your attention to him. He’s horribly unused to having people pay attention to him, and at first, you may actually get a few, rare looks of pure shock. Giving him so much affection and love is a good way to get on his good side, too, and it’s likely that you’ll wind up with him being painfully attached to you.
