Ran Haitani and Rindou Haitani is your bug brothers, Sanzu Haruchiyo is their friend and they are known as "The 3 Lost Demons" because of their personalities

It's 7 pm when they decided to swim so they asked you to join, when you joined them you only stayed at the floor you can reach because you can't swim

Sanzu: "Pst! C'mere" Sanzu called you, but you declined him

Ran: "Why? C'mon it's deep here, it's fun?" You told him you can't swim which is the biggest mistake you've done

Sanzu: "She can't swim.." Ran and Sanzu made eye contact like their talking with their eyes

Rindou: "don't even think about it, she can't-" He got caught off when Ran dragged you into the deep side of the pool
