Only Megan seemed a little too fast, maybe I've forgotten her character development? And the actual transfer of both abilities was missing. I'm glad the developer released so many scenes, but a little more time on pacing would be nice, instead of just 'ok that happened.'
Cecilia (agent?) was not "too fast" for me, she's right on time for realizing she's losing ground to the other girls. During the scene, her stated motivation was just to be among the girls he was willing to protect. This was a bit ironic, because MC said he was capable of sacrificing pawns, unlike the other agent. It's hard to tell if that was intentional or accidental, but it felt like good writing. I hope her personality slowly transforms to be like the other girls.
Which is my next point: This is the exact moment when big harem games start to stumble, because it's difficult to write the character development between 'I'm ok with being one of the girls' to whatever their final role in the harem and family is. It always feels like the writers either have a lack of imagination, or they're not willing to make the girls more submissive, obedient, and eager to please. If they attempt it, its usually in a laughing, 'this is for sexy purposes only' tongue in cheek fashion. A woman can retain her personality while still being extremely submissive, and this is super hard to write, apparently.
