In his previous life, Theo failed to protect his beloved younger sister. Reborn into a new world, he vowed in his heart, “I will never lose anyone again.” He saved a girl who had lost her parents to bandits and took her in as his adopted younger sister. He risked his life to protect a saint targeted by assassins, narrowly surviving thanks to her healing magic. Theo’s wish was pure and simple: he just wanted everyone to be happy and smiling. That was all he ever wanted. But… “Brother belongs to me.” “I will absolutely make Theo my husband.” The heroines he saved have, before he knew it, begun to harbor a dangerous level of affection for him. This is a love comedy clouded by intense, heavy emotions—a story about the girls he saved gradually breaking down.
