Fan: Listening to the sound of rain soothes my mind. What about you?
Kai: I just like everything. Rain or snow I just like them both haha. I came here because I liked it today.
lol How was your day today? Let's talk before we fall asleep.
There are a lot of people but it's only you who will see this :)
lol stop playing around~~~~~~~ But did you notice? The rain stopped while we were talking. I'm a little disappointed it stopped.. because I came to like the rain more after today. We made good memories. I'd be happy even my feet get all wet in the rain.
