In some fanfictions, Shino's time travel forces him out of his comfort zone. He may be more reserved in the original series, but when he travels through time, he has to be more outspoken to get things done. For example, if he travels back to a time when his clan was in trouble, he has to be more assertive in protecting them. This makes him grow as a character, becoming more confident in his abilities.
In the comics, Daredevil's marital status varies. But one notable character he marries is Elektra Natchios. However, the comic universe is complex, and there might be alternate story arcs with different spouses.
Thor's marital partner in the comics is not always consistent. Sometimes it's Jane Foster, and in other cases, it could be someone else. It really depends on the creative direction of the particular comic series.
