One day, when two long-time friends went out to eat on the weekend, they got drunk and became a hot topic of discussion. Recently, a hot topic on SNS is "couple exchange", a method of eliminating genderlessness. The two groups decided to try it and immediately got excited about cooking and watching movies. They just needed to touch it and get it right away. The first couple exchange has ended, next time we will exchange couples during the hot spring tour.
