#why does the magazine call taiyo an asano!! why

[sage-reads-things]

Taiyo, honey, you've gotta stop assuming that you're some nobody with a stun gun. He looks so shocked that someone knows his name, which is especially baffling since he just had a huge bounty on his head AND a viral video AND a super high-profile wedding in rapid succession. “Why does he know my name” He's a a spy!! You're all spies!! Obviously he will know your name!!! You're a Yozakura now, buddy—you're a person of interest whether you like it or not!

Also, this brings up a question I had: is Taiyo still going by "Asano" instead of adopting the Yozakura surname? I had assumed that the wedding reception would solidify Taiyo's legal status as a member of the family, so Taiyo would start using the Yozakura surname—if not in public, then at least amongst other spies. Is he still legally an Asano? Is he even registered with the Yozakura name within the spy community's collective records? And if that's the case, how official or binding is his and Mutsumi's marriage? I wasn't expecting him to legally change his name since they've still got their public-facing lives to consider (especially being underage and still in high school), but I thought that the spy world at least would recognize the change! We see later that previous Yozakura husbands took the Yozakura name, so what does Taiyo keeping his original surname imply about the validity of the marriage?
