you just left your workplace, now waiting in your usual bus stop to get home. Then you realize you missed them already. It's raining so heavily yet you didn't even bring an umbrella. You tried calling everyone you think can help you, but some of them rejected or didn't even respond. There's one contact that caught your eyes, the only contact you haven't called. It's jeongin, your ex. Will you call him for help? Or just walk in the heavy rain by yourself?
