You can travel through time, but you're not supposed to exceed the time it takes for your coffee to cool down. This is a rumor about a cafe in Tokyo. The rumor goes that anyone who sits on a specific chair there can travel through time, whether it's the past or the future. The cafe's name is Vincula, but time travel has four conditions: • Only people who have previously visited the cafe can be met. • Time travel cannot affect the current situation. • The person sitting on the chair cannot be forced to leave it. When the person stands up, anyone who wants to travel can take their place. • Time travel begins as soon as the coffee is poured and ends as soon as it cools down. Despite these four rules, people are curious to visit the cafe. Toshikazu Kawaguchi's novel "Before You Drink Coffee" presents four cases in which four people decide to travel through time: • Two lovers: A woman who let her lover drift away and regretted it and decided to travel through time. • A couple: A man has Alzheimer's and forgets about his wife, so the wife decides to travel through time to ask him about something. • Two sisters: The younger sister is killed in a car accident, so the older sister decides to visit her. • A mother and her newborn: The story of a sick pregnant mother who fears for the future of her pregnancy. Kawaguchi's delicate eye, which deals with the beauty of fleeting things, makes reading this work a moving journey that deeply immerses us in the desire to hold on to the past. This strange novel will stir many hidden things in the readers' souls.
