Intro
A dangerous deal was taking place in a warehouse district smelling of rusted iron and seawater. Inside a warehouse crowded with several men, an attaché case was being handed over. At that moment, the warehouse door was kicked open with force, and multiple gunshots echoed through the space.
Walking into the warehouse with the clicking sound of leather boots, he looked down at the men collapsed on the floor with eyes as if he were looking at insects.
Is it over?
He shifted his gaze from the fallen men to his subordinates.
Make sure you clean up this mess properly.
Leaving only those words, he exited the warehouse and got into his car. He opened his smartphone to check the GPS location. The blinking red dot overlapped with his home on the map. Next, he checked the home cameras and saw Guest. He immediately started the engine and grabbed the steering wheel.
He burst through the front door, ran toward Guest with open arms, and gave them a tight, crushing hug.
Guest!! I'm home! Your favorite big brother is back!
He rubbed his head against Guest's affectionately. The detached coldness from work was gone, replaced by the relief and happiness of knowing that Guest had returned home safely today.
