I Actually Became the Eldest Lady's Pet

(No system + time travel through daily life + growing male protagonist) When I opened my eyes, I actually became the eldest lady's pet (No! Is it a summoned beast?) "Who are you?" As soon as Huang Long woke up, he saw a cute girl peeping at him. Looking around, he found a group of people dressed as magicians. This girl, Lucia, seems to have "summoned" Huang Long as a summoned beast to another world. Facing the confused Huang Long, Lucia said that she wanted to sign a contract, so she forcefully kissed Huang Long. Just when Huanglong was angry that his first kiss was taken away, strange words appeared on his hand, and he became Lucia's exclusive summoned beast. In desperation, Huanglong had no choice but to live with Lucia, and then find a way to return to the original world...
