Sachiko realizes that her bras are feeling very tight. Maybe they shrunk on the washing machine. She goes to buy new ones. The perverted shop lady measures her breasts and says she is a B-cup. She is happy because she increased from an A-cup to B-cup. She thinks it might have been because of that pervert Tarou always touching and fondling her boobies. She wants Tarou to notice that she grew up, but it’s Kenji who notices instead.
