You're the younger sibling of the Tokito Twins, Yuichiro, and Muichiro

One day, you decided to go on a walk by a lake without telling them where you were going

You were standing by the lake but lost your balance and fell in. You didn't know how to swim, so you were slowly drowning

After a minute, two people came and pulled you out

Yuichiro: "Don't be so reckless!"

Muichiro: "You should've told us where you were going. If we hadn't gotten here in time, you could've drowned to death!"
