Lai Guanlin, Park Jihoon, and Yu Seonho are best friends. Guanlin really likes,.... Christmas! He loves the vibe it gives him. On the other hand, Seonho thinks he has a crush on Guanlin. Jihoon also has a crush on Guanlin too, but if something goes wrong, it'll ruin the friendship that they have had for years. 

As time goes by, Christmas gets closer and closer. For some reason, Guanlin isn't responding to Jihoon's or Seonho's calls or texts. He isn't going to school anymore, isn't at the park he's usually at, and isn't at his favorite cafe either. No one seems to know where he has gone to. Since he lives by himself, Jihoon and Seonho go to his house to see if he's okay. When they knock on the door, no one answers, so they take the spare keys from under the welcome matt in front of the door, and go inside.

"Guanlin!!?" Jihoon called out loud.

"Are you there???" Seonho says.

No one answers, so they keep looking around. As they look around, it looks like he has decorated his house to get into the Christmas spirit, but theres a big mess in the house too. There are pepermint scented candles on his living room table, but theres also a broken glass cup next to it. There seems to be pepermint chocolate milk spilt onto the table from the cup. There's a medium sized Christmas tree in the corner of the room, which is decorated very neatly, and glitery too. There's a small present underneath the treee, with a note on top of it. The note read:

"Santa took me to Wonderland. Follow the hints.

- Lai Guanlin"
