いびってこない義母と義姉 [Ibitte Konai Gibo to Gishi] #5

This is the first volume of a manga series about a young man who moves in with his stepmother and stepsister after his father's remarriage, only to find that—contrary to the typical trope of harsh treatment—they are unexpectedly kind and affectionate toward him. Published by Ichijinsha in 2023, this collected edition kicks off a heartwarming family comedy that subverts expectations of the 'evil stepfamily' dynamic.
