MKON-130 — My Sister-In-Law, Tsukino Kasumi, Is A Neet In Her Late Twenties With Low Self-Esteem And A Former Honor Student.

When Fuku returns home for the holidays, she finds her sister-in-law, Kasumi, a former top student and employee of a major corporation, withdrawn from society after suffering a mental breakdown due to overwork. Her family urges her to seek treatment, but Fuku feels that Kasumi has broken down from forcing herself to act a certain way. One day, Kasumi suddenly says, "I'm sorry I'm such a useless sister-in-law." Seeing Kasumi's empty expression, Fuku worries that she might die if left alone. At that moment, Fuku desperately tries to think of a way to give her sister-in-law a purpose in life.

Kasumi, with low self-esteem, says, "My naked body has no value..." but Fuku denies it and pounces on her boobs...
