traveled through from an apocalyptic world where he was a doctor who had healing powers, and was a big leader. One of those "die with the zombie king" type of cliche backgrounds. They didn't spend a lot of time explaining this background. It was mainly used to explain his OPness of being a miracle doctor who had surgical knowledge as well as knowledge of Chinese herbal medicine and acupuncture. He was also very knowledgeable in martial arts and poison... all attributed to his prior life. He did not bring his powers with him nor his prior strength. The 15 yr old body he woke up in was a weak ger who just had his engagement canceled... drama right off the bat

ML was saved by an old man when he was abandoned in the mountains as an infant. The old man gave him to his son to raise, and that lasted until the old man died when he was 7. He was then kicked out to live on his own by the rest of the tr*sh family. He genuinely considers the old man his grandfather who was truly good to him. ML and MC marry due to a marriage fraud and he is 17 (ML says he is 16 or 17, but it's been 10 years since his grandfather died) at the time of their marriage. MC decides to stay married to him because he is a very honest and good person, although they are married in name only for quite awhile before MC falls for his sincerity and decides to make it a real marriage. ML's "luck" changes after he is married. More and more good things come his way and those who are bad to him and MC start having bad luck and self imploding. His luck is so good that his fields produce more abundant rice and fatter fish and his rice tastes better than others rice. There's no explanation for this other than he is blessed or lucky

You have your transmigration from zombie apocalypse, rags to riches by introducing Chinese cuisine, orphan husband becomes prince, miracle doctor, farming, face slapping, imperial intrigue, conscripted into war and becomes general, and a huge protagonist halo where those that are good to MC have (mostly) good things happen to them and those who have bad intentions fall into a ditch and break their legs

A character's engagement was broken because their family plotted against the MC and the dirty water bounced back on them. So later when the MC started making money, they came up with the bright idea to have the ger try and seduce the ML to become a concubine... which backfired and completely ruined their reputation. Then later, MC's ger cousin (whose marriage was also canceled thanks to their plots against MC backfiring) also decides to double down and see if they can marry in as co-wife... because obviously the other person failed because they were practically strangers with MC and hey, I'm family

there are two parts to this that bug me. The first is everyone's insistence that his husband will leave him if he doesn't have kids and that only by having children, especially male children, will his life be secure... when he's the main breadwinner in his family AND the ML has made it clear with both words and actions that no one will come between him and the MC, children or no children. The second is that as a doctor he keeps thinking that it is not healthy for his body to have a kid while he is still a kid himself, plus by this point he knows his husband is a prince and doesn't want to have a kid until that danger is cleared up... then suddenly decides this is making his mom sad, so hey let's go ahead and have a baby now to make everyone happy!

I mentioned their ages at marriage for a reason. 15 and 17. They go through at least 2 rice harvests together and a New Year before ML is conscripted (so they were married at least 6 months if not longer). MC spends about 6 months apart from him between traveling and training (he snuck off and joined up to follow the ML but was sent to a different training camp) before finding him again at the front lines. They separate again for another 6 months. During this time they show MC's parents celebrating another New Year. 2 months later they leave the army and return home. At this point it is mentioned the soldiers he trained with have a little over a year before their 3 year conscription is up. They spend at least a month and a half before they decide to get pregnant (this is demonstrated by a new group moving into the village that mentioned it took them a month of showing their sincerity to get approval to move in, then a swine plague where MC and ML spent at least half a month helping to treat and disinfect a village). Also at this time (before NI decides to have a baby) he mentions that he's had 2 years of profit from the tofu business. This would put him around 17 when he gets pregnant and ML 18-19. He is 3 months pregnant before he gets summoned to the capital, and they travel for 3 months to reach the capital... now here is where we start seeing the discrepancy. Everyone describes both him and the ML as 16 while in the capital. Later, it is mentioned that the prince who is the same age as the ML is 17
