Yuuwaku Scramble by Moonstone Honey eng,jap

Haruto is an ordinary student, and his mother got married again once. Then she left for her honeymoon, and left him in the house of her new partner, where he was reunited with his childhood friends, sisters Asuka, Yuki and Miku. He was glad to live with them, but also worried about whether they would be able to open to each other.
Three sisters greet him with cordiality, but because of their different characters, they end up competing with each other instead. Each of them wanted to be the one to take care of him, and he fell into a fight between three lovely sisters, which became both joy and difficulty.
Since they live under one roof, their feelings for each other become more affectionate, passing from kindness to love. What will Haruto's relationship with the three sisters end up when Christmas comes?
