This cute excerpt from the "To You, Sweetheart Valentine ♪" event! (♡´౪`♡)
Basically, Pastel*Palettes needed to make chocolates for Hina, and she wanted "rururun chocolate". They asked sayo if hina ever said"rururun" around her, and she told them this story:
Sayo : Yes, at first I also wanted to ask my mother to become the model for the drawing. But then, Hina suggests that we draw each other, so in the end, I drew Hina and Hina drew me.
Aya : Hee~ so you drew each other. You guys were close even in childhood, huh?
Sayo : I wonder about that. Anyway, Hina was the one who got to draw first, and not long after she started, Hina finished her drawing. As for me, I just can't get the drawing right... at that time, deep in my heart, I'm afraid that Hina would say that she's tired of becoming the model.
Chisato : Certainly, I can imagine Hina-chan being bored halfway and starting to move.
Sayo : Yes. But, the weird thing is, she just stood there motionlessly, waiting for me patiently until I finished my drawing. Then, after I finished my drawing and show it to her, her eyes lit up and she said "I want this drawing that Onee-chan made with all her heart."
Aya : Eh? Even though it's for summer homework?
Sayo : Yes, I need to give it to the teacher, so of course, I refused her. But even so, she still insisted. So I promised to give her the drawing after I get it back from the teacher.
Sayo : Then, just like I promised, I gave it to her and she keeps it in her desk. It's something that I made for homework, so I don't think too much about it. But to Hina, it's something priceless.
