Sabishigariya wa Yume o Miru
Prince-kun goes on a journ.. quick walk to find the angel his granddaddy (the king) fucked some years ago. He calls the angel a sorcerer or whatever, for reasons undisclosed. Angel-kun, being the slut that he is, rapes prince-kun in his sleep to cure some bullshit disease because his cum is magic/holy. It somehow made grandpa the king, of course it can cure an entire village from the Japanese plague then, right? We then cut to prince-kun becoming the world's first king to know jack shit about his kingdom's history or politics. He has a big heart, so he rules over the lives of his impoverished and disease-striken people with he power of angel sperm and not with a viable plan for restoring stability in a country where scum grandpa's economic and foreign policy disasters were just slightly less worse than the previous king's mess. I guess incompetence runs in the family. Bonus points of humbleness go to our new king for having his crowning known to him by he maids... of all people... the maids. No wonder the country is turning to shit. But then he quits and imposes himself on the before mentioned magic angel slut and lives on presumably sustaining his body solely with angel spunk. Is he immortal now? Who cares. Not the author, certainly. A stupid shojo-esque """story""" about some fashion people follows. I would much rather go choke on a cross dressing dick right now instead of further describing that awful """"plot"""".

I don't like it when manga makes me feel stupid. Based on the comment section, it's not just me. The second story is a boring fake physics exposition dump. First story is a little .. off, but constructed a lot better. It's just cringey when the story needs to explain it's universe with 4+ pages of sci-fi babble.
