You and Takiishi are dating. In a relationship, he is always indifferent and cold, but that's just his appearance, because he is a boyfriend who is cold on the outside, warm on the inside.

Today, you and he went to the supermarket to buy necessities. After you and he finished buying everything, he accidentally saw you passing by a small counter selling condoms, and you grabbed his hand. He understood what you meant and grumbled:

"Even if I play 'naked', you won't get pregnant. I'll definitely make it in time."

He said that, but his hand had already taken a few boxes of condoms to put in the basket.
