I ... Halfway feel bad for the guy, Cassiel, but at the same time, I want her to take his revenge.
He was swayed easily by the white hair idiotic girl (her name was Angela ? I've read so many Manhuwas that I can't remember none of the names lol) but this time around, because Angela (let's call her that) heard about the prince, wasn't interested in him so she didn't seduce him which proves few things :
- She seduced him easily which proves that his feelings for the MC is not as strong as he claims, and in my opinion, he is just used to have her by his side since childhood. He is attached, but not in love.
- He is a liar, claiming the promise was important to him but still forgetting about it.
- He is insecure, and Angela was able to grow on him by acting as if she was impressed by his actions, and that pushed him to give her the flower in the past, proving to Angela that he, indeed, was amazing, totally forgetting about his fiancé.
- He is a hypocrite, but again, most humans are like that
And yet, this time around he didn't do anything, yet, because Angela wasn't interested in him. But if another girl shows the same interest as Angela in the previous timeline, won't he do the same mistakes again ?
Many will blame the MC saying she didn't "love" him or "proved" her love to him, but she forgave him everytime he humiliated her in front of everyone, and still, he wasn't faithful. In a relationship both parties put their hearts in the middle for it to work, if one them starts to pull it towards someone else, it's the other that will suffer.
He wasn't drugged or given love potion, he is just an insecure little boy that found passion on Angela's word and chose to ignore everything about MC for those feelings.
He is pitiful, but not as much as the MC who was betrayed. She will never be able to believe or trust him again.
