The sudden reward startled Leon, as he wasn't prepared for it at all.
He couldn't help but think about how many years ago he had already had everything with Tassera... The same applies now, with three women by his side: a queen and two princesses. If finding a spouse were supposed to give him a Golden Finger reward, he should have received it long ago.
Leon thought about it over and over. He could only understand it as he never truly cared in the past; he was just playing around. It wasn't until this time, after getting to know Tassera's family, accompanying her to inform other Blue Dragons, exchanging assets, and going through complicated courtship and mating ceremonies, that he finally recognized Tassera from the bottom of his heart, wanting to be with her for a lifetime, and had this feeling of wanting to start a family.
The Blue Dragons are loyal to their mates and family, so choosing a Blue Dragon is no problem.
