4.0 or 4.8, less than 5 because their first time was NOT consensual, he was in a intoxicated state (heat). Despite the cute story and art style, non-consensual sex is a turn off always. It’s endearing that the king began to take sou’s feelings into consideration (which should’ve been the main concern in the first place, regardless if he misinterpreted any invitations to continue), warming him up to affection so that they could finally consensually be one.
