so im asian, to be more exact i live in malaysia, age 22,

my main objective is to use the pheromone to get my ex back again, we r still friends, so we always with each other, i just need to get some spark going again.
i've try 2 spray chikara + 2 drop of NPA, and i have try 2 spray chikara + SOE but i dont see anything changes, body language or anything.
