Who gives me the general meaning of the song アイのシナリオ (Love Script)? _(:з」∠)_看了pv有点看不懂,主要是pv

It's a NTR story

In a past life

The second man proposed to the female lead, and the two were already living together

The male lead communicated with the female lead through a window, and the male lead was NTR'd

The second man found out, and then he beat up the female lead

The male lead saw this, and then he said at night, "Forever together, I will watch over you. I'll protect you" and ran away with the heroine

When he was looking for the heroine, he said "I'll make you suffer one day"

Later on, he was reincarnated

The heroine's soft-looking boyfriend was the hero from her previous life

He just pretended to be honest and lied to her. He was only pretending to be honest and cheating on the heroine's feelings

The hero found out and beat up the second man to break them up, but the heroine stopped him

Later, the heroine heard the second man admit that he was cheating on her

Then she bumped into him in the corridor, so she apologized and said that she misunderstood him

The hero said, "I'll always be there to protect you,

Wasn't it already a long time ago? The woman said, "What?" and the two of them got together

At the end, when the man took the woman to find the second man, the second man said, "I've been waiting for this for a long time."

Here are the two men who remembered their past lives. Only the two men remembered their past lives

By the end of the PV, the heroine of the past life suddenly opens her eyes, so she should be able to foresee what will happen after her reincarnation

The red necklace is a proof of the hero's identity, and the one who carries the red necklace is surely the hero

The last words indicate that he has already remembered what happened in his past life, and that he is waiting for the hero and the heroine to come to him

After his reincarnation, the hero deceived the heroine about his past life, and then he said "I'm tired of waiting. The woman's feelings is what he said in his past life, "I will let you meet with misfortune one day."
