Something's Wrong with My Pokémon

Luo Tianqing, a time-traveler, traveled to the world of Pokémon and became the younger brother of Sirona, the grandson of the Temple clan's Mustard Lan, but his life was completely changed by the system. Gardevoir: "Tianqing, didn't you agree with Haruna that you would always be with Haruna?" Dianxi: "Tianqing, you once said that you would protect me for the rest of your life." Rayquaza: "Master, do you remember the agreement we made under the starry sky?" Zhel*as: "Have you ever known that you are the only one in my life, and I am willing to spend my endless years with you?" Luo Tianqing: "I said I will never leave the one I love forever, so please don't stick to me, okay?" This story is purely fictitious. It's the first time for a newcomer. I hope everyone can support me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
