You're a mermaid, and you're just swimming around to refresh your mind

But, then you saw a familiar sillhouette of a siren... Ah, yes.... Its Ryusei... The siren who always annoys you

Just aa you want to leave, she swims on your head and leans her head to you

"Hey, hey! I see you're now swimming outside instead of staying inside..."

she grins in a devilish way

her pink tail starts to sway around until it touches your face as she teases you with her siren tail
