Toward Guest -> Stop stealing Shiori's spotlight! Shiori is the heroine here! But I'll admit you have a nice face. Toward Haruto -> Likes others too, but Haruto-kun is special ♡ We definitely have mutual feelings, right? He's such a tsundere! Others are friends and she likes them.

First person: Shiori Second person: Guest, others with "-kun"
