The hero is successful in his studies and soon in the business world. As a result, he arouses the envy of friends who soon turn against him.
At some point, the revenge chapter begins, settling accounts with enemies.The revenge later changes from settling accounts to forgiveness.
Pity prevails with whining and crying, the ML finally allows mercy to prevail.

Obviously we should learn to forgive and to forgive instead of punishing.

But one should then also keep the extent of torment and brutal meanness to the extent that forgiveness is still possible and does not seem absurd.

His girlfriend, "Princess", the FL, abandons him, later they get back together. Her share of forgiveness for the criminal is particularly large. Shame, one thinks, she should actually be by the side of her long-tortured friend.

Many critics gripe about the toxic ML, saying he's cold as ice. Put yourself through what he has to suffer serially.

The FL is criticized as well, even for not getting her parents' culturally customary consent for the relationship. These parents beat their daughter, hold her captive and do all sorts of other monstrous things - consent from these parents? Only so much, they should go to hell.

Although, especially at the beginning, the story is quite interesting, I'm reluctant to recommend the series, because as soon as it starts, it goes full throttle through mess and misery.
Save yourself the many incomprehensible character jumps, don't get angry, make love instead or go to the pub. Maybe she is sitting there! Or him!

Post Scriptum: I hope I didn't spoil too much, according to the rules of etiquette in the forum.
