Well, I wouldn't say that... Simply because these doubts actually helped make the relationship more built? Like, now Rix is able to admit to himself that he infact has feelings for Nuah or Nauh.. ╮(￣▽￣)╭
Not to mention that he would've found out about the powers of the divine beasts eventually. I think it's better for him to find out now, while they're still just "friends" instead of finding out about it when they're already a couple. At least now they can start this relationship without this huge potential for a big misunderstanding.
Ohhh myyy goddd Yes. Yes. Yes. YES

Banam I love you but man you're a dick for planting doubts inside Rox's heart. WHAT ARE YOU PLAYING, HUH? Are you truly trying to protect Nuah??? (︶︿︶)＝凸
