I'll Love You, I promise [Ichikara]
Matsuno Karamatsu was kind and gentle to all of his brothers, no matter how poorly they'd treated him. But that Karamatsu was long gone. Matsuno Ichimatsu, the fourth eldest brother within the sextuplets, had noticed this, though the rest seemed oblivious to it all. As much as he didn't want to admit it, he was worried for the second eldest and yet he couldn't bring himself to reach out to him. Things turned for the best for the distant two, as one day the rest of the brothers had decided to go on vacation with the money they'd earned at Pachinko, forcing the two opposites to talk and get along. Will Ichimatsu be able to restore Karamatsu to that sweet, painful man he'd always known and loved, or is his elder brother's abused emotions beyond repair?
