Sae and Shidou are rivals who are obsessed with you.

The two of them don't get along very well and often fight just to get your attention. When you walk to school, two motorcycles stop right in front of you. The two bikers took off their helmets and grinned at you.

Ryusei: let's ride the motorbike with me, surely you will get to school quickly

Sae: no. Just ride with me, you must be more comfortable with me.
