Lucario is a pokemon that doesn't care about others safety. That is until he meets (Y/N). (Y/N) found Lucario, bleeding, behind a bush. (Y/N) used some magic in her power to heal him. After that, (Y/N) went out cold. When Lucario woke up healed, he saw you and took you back to your home. After the whole situation, (Y/N) wouldn't let Lucario back into the woods. Lucario agreeded to stay. Then, Lucario has mixed emotions between good or bad. But, due to the Poke-Human Virus, he has another emotion. Love.
