Sakuramoria

— Maybe she wanted to be a "gray mouse" for her own reasons, but in certain situations, she simply couldn't remain inactive. In reality, Futaba is resourceful, decisive, and responsible. This became apparent back in April when she saved her mentor from a maniac who had harmed two students. Okay, let's assume she was just lucky to be nearby at the right moment. But no one expected her to run for student council president, and her campaign speech was quite effective and well-thought-out, hardly relying on divine help. And even at that ill-fated ceremony, she tried her best to reason with the old man when he started threatening his classmates. That's why I don't believe in her treachery; everything she did was an attempt to protect her own, to make the lives of those around her a little better, and to fill them with meaning as much as she could. Well, you can judge her external attractiveness however you want; it's a matter of taste...
Gideon took a breath, drank some tea, and continued.
— As for the king... I don't know, maybe he has some dark plans or personal preferences regarding his chosen one. Maybe she has something that particularly appealed to the old man, and he simply fell head over heels like a young fool. Of course, this doesn't excuse him, but... anything can happen; I wouldn't rule out that possibility.
