here’s some spoilers

right where we left off:
Gallico used the death of queen (his aunt) to try to start a war unless King Leo agrees to send ML to his country for meeting. To save his own skin, King Leo sent his own son on a small entourage of 20 knights to Gallico. ML didn't want to leave MC but felt he has the responsibility to save Sir Elko too.
- With ML gone, MC focused on growing her personal wealth and reputation. As she knew a plague is coming soon, she pawned her blue diamond to receive huge loans to buy up the grains. Meanwhile Cesare was promoted to be the King's legitimate nephew and the next heir should anything happened to ML at Gallico.
- ML and his men received hostility when arrived at Gallico and ultimately was put on house arrest in the palace. Sir Elko was returned to ML, only after they cut off one of his arm, blinded and deformed his body.
- King Philip plans to slowly poison ML and his men, while his army is already starting to conquer the Estruscan borders. Lariessa knew of this and proposed a plan to ML. She will help them escape, only if ML will sign on a marriage certificate with her.
- ML signed the paper for the sake of rescuing his men (they were not aware of this condition) and escaped Gallico by pretending to be part of the Holy arm on their way to conquer the pagan's land. They were caught and in exchange to not being sent back to Gallico, ML and his men pledged to fight in the Holy war.
- MC learnt of ML's escape and joining the Holy war. She keeps writing to him but receive no reply.
- Cesare was promoted to be Duke Pisano. In his mother's ambition to raise his son's to heir position, he was sent to fight off the Gallico soldier at the borders which ended with humiliation.
- MC decided to help him (I forgot what's the plot but Cesare became victorious and hero of the country). Cesare became the knight commander of the kingdom.
- MC also sent some of the near-death plague patients (they volunteered since they are going to die anyway) to Gallico which cause the plague to spread to Gallico and ended the battle on the borders. MC's hand was now full of red spots due to the number of deaths caused by her action.
- The King soon learned that MC had amassed a lot of grain stocks which was important during this war and plague time. He tried to get his hands on the grains by forcing MC to marry him.
[ MC was called to the palace. Thinking it was just a normal audience with the King, she went but realized it was a last-minute wedding later.]
- Having heard the news from his disgruntled mother, Cesare brought his knights and gate crashed the wedding. He forced the King to change the groom's name to his name. The King changed the name to Cesare but announced them as engaged couple instead of marrying them. (selfish old man refused to hand the wealthiest woman to his son).
-Hence MC became Cesare's fiancee but Cesare was now in bad blood with the King.
- The King fired Cesare from the knight commander position and put him on house arrest as what seems like an initial step to execute him.
- Cesare ride his horse to MC's home under the rain and seek her solace.
- MC negotiated with the King and managed to stop the king from punishing Cesare in exchange with some of her grains.
ML was a skilled swordman and had win one battle after another. But they were short on money and supplies.
- MC found the late Queen's huge slush fund which she had accumulated for her son. MC couldn't trust anyone to deliver the gold to ML except Rapheal. (By now, Rapheal had became very close to MC and was secretly in love with her.) He traveled across continents to deliver the gold and MC's letter to ML. Unfortunately ML was called away to emergency battle and Rapheal passed the gold and letter to Sir Elko.
- No one knew that Sir Elko was brainwashed by Lariessa's father (Grand Duke) to prevent ML and MC from reuniting. He had hidden all the letters from ML to MC and vice versa. He passed the letter that ML wrote for MC to Lariessa, who in her delusional state, add an L to Ari's name and pretended that ML wrote those love letters to her.
- Sir Elko also lied to ML that the gold that Rapheal delivered was from Lariessa's father.
- Some time had passed and Ariadne seems to get used to being Cesare's fiancee but she still distrust him. Cesare wanted to have more skinship with her and planning to propose to her in a room during a ball. They were intimate and the outer layer of her gown were removed, until she stopped him. Cesare was disappointed but didn't pursue further. Unfortunately he accidentally tried to help MC remove her glove (which hid her red dots), she panicked and slapped him. Rapheal appeared and thought Cesare tried to assault MC when seeing her dishevel state. Fight broke out and Cesare was upset that MC didn't side with him. They went on cold war for days.
- Isabella went to Cesare's home and showed him the letter she stole from MC (unsent love letters she wrote to ML). Cesare was drunk and burning with jealousy, he ended up having sex with Isabella.
- Cesare kicked Isabella out after the sex. However, Isabella managed to steal MC's handkerchief from Cesare's room and stain it with her blood.
- He made amend with MC and prepared a big birthday party for MC. Isabella appeared at the party and threatened to show the handkerchief to MC (as proof that she had sex with Cesare). UNable to withstand her tauntings (about how Cesare failed to entice MC), Cesare had sex with her again and as Isabella planned, the curtain fell off and everyone at the party witnessed them doing it.
- MC left the party and Cesare went to De Mare mansion to beg for forgiveness. He talked about how he thought Isabella was unattractive, with flat chest like a man. This totally brought up what MC's memory of TL1. In TL1, Cesare said that her breasts were too big like a cow.
- MC finally broke up with Cesare. He was heartbroken (though he deserved it), retreated to his duchy and wasting his life.
- 4 years had passed since ML left Entruscan. ML fought very well in the Holy war and had amassed 800 knights who pledged loyalty to him. He returned to Estruscan as a hero but was unwelcome by his egoist father.
- Before ML and his troop entering the city, Sir Elko pretended to be ML and wrote a malicious breakup letter to MC, declaring Lariesa as his wife. MC was heartbroken but decided to watch ML from afar during the parade. Rapheal accompanied her.
- MC had a breakdown when seeing ML from afar and she was led away in Rapheal's arm. ML caught sight of them and was jealous.
