Lee Kwang Soo has only been on Bubble for a day, but he is already showing just how seriously he takes talking with fans.

On October 2, the actor began sending messages early in the morning, with his first one arriving at 7:28 a.m.

He wrote, *“Guys, wake up. It’s time to do Bubble.”*

When one fan jokingly told him to go back to sleep, Lee Kwang Soo replied, *“No. You’ve slept enough. We have to do Bubble.”*

He kept the same energy with fans who said they had other plans. When one person said they were attending a sports festival, he answered, *“Finish the sports festival quickly and come back to Bubble.”*

Another fan said they were doing their makeup, prompting him to reply, *“Finish your makeup quickly and come back to Bubble.”*

Even when a fan asked for encouragement before an exam, Lee Kwang Soo unexpectedly answered, *“I’m hungry,”* adding to the playful mood of the conversation.

His enthusiasm had already started on October 1, the first day he joined the platform. While setting up his profile, he chose a background image featuring his own face filling the screen.

After fans joked that he was talking too much, Lee Kwang Soo asked, *“How many messages a day is considered appropriate?”*

He later admitted, *“I can’t stop,”* and *“I keep opening and closing the Bubble app. I think I’m addicted to this.”*

When fans encouraged him to sleep after chatting late into the night, he joked, *“Even if I fall asleep, I think my thumb will keep moving a little.”*

His sudden enthusiasm quickly reached fellow celebrities as well. Kim Woo Bin reacted through his own fan platform, asking, *“Kwang Soo hyung started Bubble?”* and joking, *“If he’s funny even on Bubble, what are we supposed to do?”*

IVE’s Rei also said she was seriously considering subscribing, adding, *“Being funny is what I’m most jealous of.”*

Lee Kwang Soo is known for his variety-show humor from programs including *Running Man*, *GBRB: Reap What You Sow*, *Yoo Jae Suk Camp*, and *Pinggyego*, and his first day on Bubble appears to be giving fans another place to see that same playful side.
