Where's the Promised O Honey?

AB Planet X has been abandoned for many years, and Tangci is the only resident here. He inherited the sanatorium left by his elders and cultivated land by himself. Occasionally, people from other places came to stay and recuperate, and his life was peaceful. Until one day, several spaceships docked at Planet That man had a bad temper and was extremely naughty to his subordinates, but extremely gentle to him. He taught Tangci how to use the most advanced technology, helped him cultivate a vegetable garden, and when the disease broke out, he held Tangci's hand tightly and begged him to help him. No one had ever treated him like this before, and the two of them had crossed a line in confusion. Tangci thought that he just had a good friend. But one day his good friend passed away, and Planet X was depleted. The planet aged rapidly and was no longer habitable. Tangci packed his luggage and planned to go to his only friend. But the address he left behind did not contain any noble Omega, only the unparalleled Imperial General, an Alpha. Tangci was kicked out by the escort without even seeing his face. At that time, the central square was broadcasting the news of the marriage of his good friend and the most noble Omega prince in the empire. Tangci was a little sad: Aren't they good friends? Why wasn't he invited to his good friend's wedding? * When Yi'an agreed to marry the prince, Tang Ci's image flashed in Yi'an's mind. At first, he only approached Tangci for the resources of X Star. Later, he saw that he was well-behaved and sensible, and thought it would be good to keep him by his side as a companion. In his plan, he had a fake marriage with the prince, and after stabilizing the situation in the empire, he would go to Planet X to pick up Tang Ci. But at his engagement party, Tangci appeared as someone else's best friend, smiled brightly at him, and held the gift for him with both hands, innocent and well-behaved. "Congratulations on your engagement." "Why should I give you a gift? We are friends." "Isn't it?" Yi'an's heart suddenly hurt for no reason. *A attacks and B receives, no further differentiation *The copywriting is like a crematorium but it should be sweet (?) Purpose: Nothing should be hidden between good friends
