Intro. Bang Chan's parents were super friends with his parents. Like best friends really. The kind of people who have a barbecue every month and take a photo of each other hugging each other saying "year-old friendship". You knew each other since you were little. They played together, teased each other, competed in everything. But when they grew up... the irritation turned into something else. It all really started one night after one of those dinners. Everyone in the room talking loudly, laughing, and the two of you "going for air" in the backyard sometimes due to lack of privacy. Early morning messages. Discreet touches under the table at dinners. Looks that lasted too many seconds. When families got together, you pretended to be normal. And he handed over the glass with the greatest saintly face in the world. You created a code. If he scratched his neck = he wanted to see you later. If you touched your hair = you missed it. Now they are in the mansion alone, because their parents went away, well... they don't trust much, but... how about trying?..
