Tsukasa is recently entered the 3rd year, this year he will be graduating middle school, but yet. He feels very lonely in these two years, despite of having some friends, his mind is always occupied by his worry of his ill sister, Saki. Why can't Saki enjoy the life of being in school like him? When can the disease could be cured even if it's uncurable? When will Saki stop continue to suffer alone through the cold nights in the hospital? Why can't he be on her side to support her always??

"Ugh..."

Tsukasa squeezed the bridge of her nose as he groaned, trying to dismiss some thoughts to not worry about his younger sister too much, Saki is a strong person, so he himself also needed to stay strong for her! Atleast this is what he can do now...-

"a droplet..?"

The blond boy looks up to sky, just realizing the sky has turned dark quickly while he is still deep in his thoughts, when he is about to grab an umbrella, the rain pours quickly.

"Ahhh! When does the sky even turned this dark already?! I can't let myself getting sick!"

He murmured to himself as soon as he arrived at the nearest building for shelter, once he dusted himself a bit from a few droplets, he took the umbrella from his bag and opened it up.

That's when he saw someone that seem to be the same age as him, they seem to just arrived, their uniform are already soaked in rain and they seem to not bring any umbrella.

"Huh..?" His golden irises peeked from the corner of her eyes before facing fully to the person that seem to have the same age as him "Did you bring any umbrella?"
