Y/N was the only one out of Tengens wives who had this effect on him. See Makio, Suma, and Hinatsuru all went on a mission that was kinda dangerous. Everyday Tengen was worried, and stressing out that they weren’t alright. When y/n noticed, she went over to him. She pulled him into an embrace, burying him face in her chest. And calming him down, telling him to let it out. And since Tengen felt safe, he did, he cried, he was stressed, he didn’t like having his wives so far away that he couldn’t know if they were alright. Tengen was so thankful that he has y/n, his shy wife that could always help anyone no matter how much they try to hide it. She’s helped Shinobu, She’s helped Giyu, she’s helped Sanemi, and she’s helped Amane Ubuyashiki when she was scared of losing Kagaya. But she always helps her husband and sister wives, Tengen, Makio, Suma, and Hinatsuru.
