I found Solis cute with the way he blushes easily... But i can't lie some aspect of his personality is my personal pet peeves so I don't love him that much, though he did redeem himself in the end so it's alright ahaha, if i rank them it would be Sekheo, Val, Solis respectively.
Thank you for answering my curiosity! Well I'm glad that they seem able to communicate or else they would be veeery lonely for centuries :"
