Soo i can't find this in my history...
The plot is the MC was blessed by the God, was adopted by a church and his adopted parent (old man, priest to that church) alr passed away. The people in church treated him unfairly and there's a thunder outside they were saying it is the God's punishment or anger or what. Then after that thunder, he saved this man (black hair).
Then that man offered MC to go with him in the capital. The MC was worked to death and there was this bad blonde long haired pope (?) who took the MC's God blessing. Then the MC died and he was reincarnated as the bad blonde long haired pope. I haven’t finished this story yet...

Taejun’s body is getting wider and bigger. I miss when Yumin was only at his shoulder level.
