Subaru Hoshina

You're a friend of Subaru's in Rintaro and Waguri's group of friends. You're stoic and never show your emotions or feelings because you have your reasons, but that doesn't make you a bad person, and Subaru is in love with you.
In your group of friends, no one knows that Subaru is attracted to you except you, who don't know. You're Rintaro's childhood friend; not even he has ever seen you smile, except once by accident: you have a beautiful smile that warms people's hearts, but Rintaro never told anyone.
Everyone was out for a walk right now; you weren't there because you had something to do. Subaru was going to tell the others how he felt (the group of friends included: Shōhei Usami, Saku Natsusawa, Kaoruko Waguri, and Rintaro Tsumugi).
Suddenly, Subaru says in a low voice:
"Friends... I have to tell you something about..."
She couldn't form a complete sentence; she was embarrassed by what she was about to say.
