An intriguing tale. I feel really bad for MC. He went thru hell in his 1st life. The emperor was an absolute tyrant, who tortured the one he claimed to love. I despised him so much. He wasn't much better in his 2nd life. Indiscriminately killed innocent girls he slept with. What's with that. He changed after meeting MC again, but his past crime was unforgivable. Also, why is he so horrible to his small son? Luckily for him MC was soft hearted. They ended up being very sweet to eachother, but it's unrealistic given the pain, hatred, resentment MC endured and the emperor still being an absolute tyrant. Would've been better if they'd both died together and starts fresh in their next lives.
