tbh he could've hugged her or told her that him and his Grandma are there for her and that she is not alone, a simple dinner with kazuya and his grandma would've been a better choice than to spend tons of money on useless stuff, she needs comfort and a place that she won't feel lonely since her only relative just passed away yet this MC just went with the mentality of "If I spend more money then she will be happy" not everything can be fixed with money.... Plus having kazuya's Grandma and the homey atmosphere will likely make a person to open up.
