When the two met, Ester was still a child (14 yo) in Morse's care; However, there was not much interaction other than an exchange of glances and things, so it was after a while when Ester grew up (20 yo) and was ready to take her first step as a guardian that they both had the opportunity to meet each other, As was protocol, Reazz, the Captain/Leader of the Knights of Risomnia, had to show him how things worked in the city (In the same way that Nath did with Lenord some time later) That was their first interaction, nothing in special, she was very charming, and he was very serious, it was some time later that he was able to observe her better from afar, his feelings for her were still confusing, she constantly greeted him, but he just stayed silent and made a terrible face of disgust, something which confused her a lot, but She didn't pay much attention to it. Reazz is not good at facially expressing his emotions due to things he experienced in life, yet he tried his best to change that.

Reazz doesn't know yet what attracts him so much to her, but one thing he's sure of is that he likes her, because he can't find a balance of his emotions when she's around. And he remains in a resounding silence that could last for hours. As for Ester, she fell in love with Morin because at the time they met, Morin simply looked at her and ignored her. Ester is a very sociable girl, she likes to talk and be very charming with everyone, she is accustomed to receiving equal treatment from the rest, however, that day that small action that Morin did to her, ignoring her, was what triggered her whim and strange love (obsession) towards him, no one had ever ignored her like in such a shameless way. She loved that.

And if they have a chance, they may have it, but it is something that is almost unlikely, after all they both scare each other away, by their actions.

He would take it more calmly, especially since it is Ester, Morse considers that Ester was always a special case among the guardians, so anything she does would not impact him much, except for the fact that she is in love of Morin, that would leave him speechless.

I think there wouldn't be many, in fact, I dare say that there is only 1 and it is not such a potential ship, sorry, although that depends on my inspiration and creativity, hehe
