Shy college student and otaku Miyako lives at home. One spring day, her little sister, Hinata, brings home a new friend she made at elementary school. From the moment Miyako sees Hana-chan, her heart won't stop racing! Desperate to make friends with the angelic Hana-chan, Miyako uses her skill at making sweets to try to lure her in, but...
Oh! That's it! I just 
won't talk face-to-face!
¡Ya sé! ¡No tenemos

¡Ya sé! ¡No tenemos
que hablar cara a cara!
Oh, giusto! 
Basterà non farlo!
Entendi! Basta não encará-la!
