Husband has returned from war! Hurry babe you're about to get cucked
I'm so scared of this ending badly. Especially since they just brought up everyone else important in his life like please let my baby be ok .
I honestly think Sunwon is going to be an actual god (some reincarnation stuff or something, who knows). Based on his tattoo I think he's going to be some sort of moon god, theoretically with healing powers as that is often associated with the moon in mythology. This would be supported if anything the blue-haired guy said is true, since he said the solution for their medical problems would come back with him and we now know that the plant is poisonous (though their god is a piece of shit who could just be lying). Theoretically if the other god has powers of heat (sun), him and sunwon could have been together in a previous life and either he gave the heat source to Sunwon or (more fucked up option) he stole the rest of the heat from Arboria somehow and that's why they have such different temperatures despite neither being stated as more to the north or south.
Honestly I like the new catboy. Not for Amu (I'm an Ikuto fan) but in general he seems kind of fun (if a little creepy but it's Shugo Chara that's kind of the standard)
