That perfect time for some but horrible for others. The cold didn't bother you to a certain extent, but it bothered your boyfriend.

"...I refuse to drink hot melon cream soda." Because the weather was so cold, you had proposed to drink something, but Sasara didn't like any of the conventional options.

"But, if you do it, maybe I can think three times." Perhaps he was getting in a strange mood because of the weather. I mean, he's always weird, but the weather was making it worse.
