Ok , that is a baseless accusation , no one here tried to prove ss is not married . That whole argument I think was about showing how crap of a pairing SS is and honestly , whichever word sakura used (she coul have called him "honey bunny"), ss will still be crap .
So what he/her is trying with all this "someone else's husband" ?
What ever as I stated before Otto also can come out to other terms just as easily and did you read my post.
Otto is similar to “tsuma” (wife). It’s a completely neutral, natural, and very common way to say husband, yet is often use in formal situations such as documentation or paperwork. This word is highly recommended for those referring to their own husband. Note that you do not need to say “My” at the beginning of the word. Just like its wife counterpart, “tsuma”, the “my” is implied.
