Help! The Yandere Alien Followed Me to Blue Star

[A formidable fighter who transmigrated back from the interstellar world as the top & a cute, clingy, dangerously lovesick alien as the bottom] Chi Mingji spent twenty years in the interstellar world, going from an undocumented nobody to a major power. At last, he completed his System mission and returned to Blue Star. Looking at his rejuvenated body and the ten billion in wages the System deposited into his account, he could see a bright future ahead. Chi Mingji planned to retire immediately. [Host, your mission is complete. The System is about to disengage. To reward you for your tremendous contributions to the interstellar world, we have prepared a golden finger for you.] A few days later, Chi Mingji discovers an impossible folded space on the second floor of the milk tea shop he owns. Inside, rows of incubation pods are neatly arranged, filled with nutrient fluid and containing hideous experimental monsters. Chi Mingji: Eyes widened.jpg. Oh no! This is... the golden finger??! Ye Tianshu's laboratory has been stolen. The entire enormous lab has vanished. He follows the coordinates tracked by the laboratory's System and finds a water-blue planet. The laboratory is here. So is the person he's been longing for, the one he's been trying to get close to by acting cute and obedient. Ye Tianshu has always been emotionally reserved, until the day his older brother brings a comrade home. The man, with his rare black hair and black eyes, gives him a friendly smile... For the first time, Ye Tianshu is swept up in a surge of emotion. He wants this person to belong to him alone. Ye Tianshu: I can help Blue Star enter the interstellar age. I have only one condition. Ye Tianshu: I want to be with Brother Ji. Humanity's leaders: Great! We'll bring the marriage bureau right over! Chi Mingji: ??? Theme: Love means learning when to stop.
