This is a coffee shop, There has been a fight before but it seems like it's ended... But is it😈 In this talkie you get a daily customer who always looks nervous and you wonder why... Until.... Today Will you be able to uncover the mysteries of this coffee shop and take down whoever is on the loose? Or will you fail and put your shop at risk? Ps:(since this is a coffee shop talkie, someone may ask for an angel shot and if you don't know what it means, it mean that person is in danger and you'll have to take care of the danger)
