Mitsuki was in love with Narumi-kun in the first place. But never dared to show her feelings. For the sake of her friend Haruka, who liked Narumi, stepped on her heart and arranged the date, but actually hoping deep in her heart that it wouldn't work. She is a very gentle and caring person, who sacrificed her own desires for a friend. The events afterwards are trying to cloud this fact, and tear her between her friendship to Haruka and her love to Narumi. Thas all I can tell after seeing first 4 eps.
