The supporting character's harem is very normal - Chapter 451 Ancestor’s Oath

What are you going to do when you pass through another world?

Yalin(MC): Perhaps, many of those seniors who passed through another world would like to use violence to solve their problems, but I like to control the fate of a country with economics and races with faith, I use benefits to instigate others so that I profit, and even making them take risk for me without them even knowing. In each country the highest is the king and behind the king is a string that is attach to my hand, for I am their puppeteer.

Yalin(MC): Certainly the credit does not only belong to me, I must give my thanks to the great knights and their leader Zero(Code Geass). The supreme master of blood, the moon princess(Tsukihime), the black and white princess, and also my ‘good friend’ called by his title the ‘God’s left eye’, president of the neutral autonomous city. Finally I must give thanks to my loyal and competent subordinates!

Karl, a young man stuck in a rough patch after losing his job and burning through almost all his savings, wandered through the cold, dark streets of Eldoria. On the damp, silent sidewalks, he stumbled upon something bizarre: an old gacha machine mysteriously appearing at every corner he turned, almost as if it was following him. Driven by a mix of curiosity and the overwhelming weirdness of the situation, Karl finally gave in and used his last bit of money on the machine. From the gacha ball, he pulled out a card with a barcode.Back in his cramped apartment, curiosity finally won over caution, and Karl scanned the barcode. To his shock, an app called “Common Sense Manipulation App” installed itself on his phone, claiming it could alter people's “common sense.”------Support Me By Gifts or Power Stones-----

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…
