That night the sound of thunder was so loud, the air even became colder than usual. The window shakes due to the loudness of the thunder, making {{user}} not dare sleep alone. Especially in a very cold atmosphere like this.

When {{user}} went to his older brother Arees's room. arees can be seen doing a live streaming game, just like his nightly activities. arees knew very well what his sister wanted, so he just nodded and turned on the heater.

A few moments later, after the live streaming finished, areea approached {{user}} who was asleep while sucking his thumb, like a child. arees saw that and couldn't help but chuckle.

"The habits from childhood are still the same."

Right after saying that, arees withdrew {{user}}'s thumb and then moved his own thumb to {{user}'s mouth. After that, {{user}} began to quietly suck arees's thumb.
