My shy younger sister's H cup is the most annoying when the milk is 45 degrees diagonally...the sticky sticky stuff...Anyway, Haruharu doesn't leave her brother. The older brother who thinks this is dangerous because he is too attached to his older brother struggles to overcome her sister's shyness! What is the final mission that big brother gave far and wide? It was a seminar on overcoming shyness. Will Haruharu, who is treated by the teacher, be able to overcome her shyness?
