Can Natsuki hold me if I weighed twice of hers

In a physical sense, it is generally not possible for someone to hold another person if they weigh significantly more than them, typically more than 1.5 times their weight. Natsuki, being a fictional character from the visual novel "Doki Doki Literature Club!", is portrayed as petite and lightweight, which would make it even more unlikely for her to hold someone who weighs twice as much as she does. In a more metaphorical or emotional sense, characters can offer support and comfort regardless of physical limitations.
