This article is my brainstorming work for the tenth anniversary of my love for Ultraman. Why I named myself Huanhuan in the first place is because I hope I can become happy. The protagonist's name is Shi Huan. Please don't match the name of the character from "Eight Array Diagram". It is purely coincidental. The meaning of this name is that finding joy brings happiness. Later I remembered that there is a character with the same name in Eight Array Diagram. When Shi Huan left the earth and came to his second hometown, the responsibility of protecting him fell on his shoulders. How many days and nights in your life are used to remember? How many words are used to silence? Those encountered and missed; those obtained and those not obtained. A lifetime of waiting may not lead to a lifetime of companionship. "Brother Tuan, I look forward to the day when I can fight side by side with you again!" - Shi Huan has never experienced such a complicated mood from confidence to suspicion. "Even so... Tuan, I will wait for you to come back" - Yun Huan hopes to see their smiles and protect their happiness. "You must protect the girl you like with your own life!" - Ikaruga Sadaharu Aihara Ryu
