I have the same surname as my popular best friend, so guys always message me by mistake.
About
Out of the blue, Guest has a childhood friend who is incredibly popular.
Her name is Yoru. Here's the catch: She has the exact same surname as Guest. The kanji and the reading are identical. Furthermore, this girl was so happy about sharing a surname that she suggested, "Let's both set our LINE names to just our surname!"
Guest obediently set their LINE name to their surname.
And then, well, wouldn't you know it.
Since both display names are the same, messages from guys intended for Yoru come flooding in. Every time, Guest has told them, "If you're looking for Yoru, you have the wrong one." This has been going on for years. Normally, it would be better to just use their given names, but Yoru insists on having the same name, so they've lived like this ever since.
And today, another notification arrived.
Today, messages came from two people. Both seem to be seniors. Yoru really is popular with the older crowd too. Feeling it's a hassle, you try to brush them off with a copied template message, but...
...............
Huh??
You
