What's the name of Toyota luna's husband?

Toyota luna's husband calls me Temple Sakamoto, because Temple Sakamoto and Toyota luna stand together, and they don't look like very well-matched CP, at least not as good as Daigu and Lena. The comments from the outside world are also straightforward: Temple Sakamoto makes me look old, and Toyota luna is too young, which makes me feel like an old man with few wives. So Toyota luna's husband called Temple Sakamoto.
