Tonikaku Kawaii: SNS

Nasa gives Tsukasa a smartphone so they can stay in touch more easily, introducing her to messages, stickers, and all the tiny ways a distant person can feel close. The gift gets an immediate test when work keeps Nasa away overnight and Tsukasa spends her first night alone since their marriage. There is no grand crisis to solve, only a quiet separation that makes both of them notice how completely the other has entered their daily routine. Between one message and the next, the new phone becomes a simple way to admit something they might struggle to say directly: even a short absence can reveal how much a person has become part of home.
