Senior Sister, I Can't Do It

Is it outrageous to be reborn three times without changing your character? No progress at all? Having been betrayed and framed several times, at least he has to become the kind of character who doesn't believe anyone, right?

I thought I found a good book, but it turns out the protagonist is a dog licker

Why does it feel like the protagonist doesn't look like a reborn person, just because of his personality?

I feel like his immortal body is useless at all

The writing is quite good, but it is too frustrating. Although the second senior sister never actively harmed the protagonist in her previous life, she abandoned the protagonist and saved that disgusting person. Although there was a reason for the incident, she cannot be forgiven so easily. Okay, I know that the second senior sister in this life is very kind to the male protagonist, and I can forgive it, but I still feel uncomfortable, and I feel aggrieved when I read it. It's good that the male protagonist kills decisively. The protagonist will not let them go if they are enemies in previous lives, but what about people who abandoned the protagonist due to misunderstandings in previous lives? It's really hard to forgive! I hope that the protagonist's future relationship with the second senior sister will be that of a senior sister and a younger brother, and not get any closer. This only represents my own thoughts and is just my random thoughts.
