no I only ship toji with his wife and suguru I bend the rules a lot for boy suguru bc toji is canonically only into women but I like him with suguru bc suguru is kind and I think would remind him of his wife’s warmth due to his caring/pitiful nature. shiu and toji are only old friends to me considering he was also around to be there when toji was with his wife but it’s obvious they don’t keep in contact outside of work as shiu didn’t even know toji had changed his name or ditched megumi etc
