Although I might be wrong but I'm leaning towards Satoshi and Jun falling in love. The interactions between Kazu and Jun seem like friends to me and Sho might be a heavy competition for Satoshi. I laugh when Sho was being so oblivious about Satoshi traumatizing Jun lols

It seems that the little bud of love inside Jun's heart is enough to awaken the life of some of the trees and vegetation in the kingdom? That makes me excited to know what will happen when Jun is truly in love. I might faint from all the upcoming lovey dovey and romantics scenes XD

Masaki is being so protective over his little brother I find him so cute!
