Fairy Tail: I Don't Want to Be the Guild Master - Chapter 33: Three Gates

After a mishap, he accidentally became the protagonist. Unexpectedly, he and the villain cultivated together and they actually became dao companions.

“If you want to be with me forever, there is only the supreme road of achievement. Are you willing to travel with me?”

“Of course I’m willing.”

……

In Li JinZhi’s view, the protagonist and villain’s coexistence should be like swords and spears facing each other, a feud.

But when he crossed into the novel and became the protagonist; when he placed all his trust in the man who was supposed to be the villain; when the other side revealed some unusual feelings to him; when he held Ye Yu’s hand to the altar, he discovered that the relationship between the protagonist and villain isn’t as dull as he imagined.

When the monotonous pattern is broken, the feelings of resentment turns into sharing a common destiny.

A protagonist reborn in another world.

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

Transmigrated into a novel she dropped was never on Qi Jianyi’s bucket list. She could still remember how she deleted the novel on her phone after reading the first 30 chapters of the book. “A book full of bullshit.” She cursed before going to sleep. Never in a million years would she have thought that one day, she would be pulled into a novel she hated.All Qi Jianyi could think of was trying to look for a way home while ignoring the plot of the novel. But where does she start? No, does she really have the time to think about it after the appearance of an annoying man who keeps pestering her? Qi Jianyi could not forget her first impression of that man. He was as cold as ice, but had a fiery temperament. Those beautiful eyes of his had once captured Qi Jianyi’s attention. But the young miss of the Qi family was too busy looking for a way home. How could she have the time and energy to care about a certain young master? However, Song Chengfeng would not stop appearing before her. He didn’t know why either. For the first time in his entire life, his mind and body were not in sync. “Why bother with her?” He whispered coldly, yet his legs already walked towards the woman who was enjoying her life. “Because I love you, Qi Jianyi! I didn’t even know I was capable of feeling this way, but I do. I love you! I love you so much that the thought of losing you terrifies me. It suffocates me. And yet… you’re not even mine.” - Song Chengfeng“Loving me only ruins you. So stop!” - Qi Jianyi
