Reciprocity
It was easy enough to tell Lovino had missed something when it came to reciprocity. Ludwig was nice enough to him, nothing to incite the violence which easily came his way.
Of course, considering how insane Feliciano was...
But Lovino would even insult his brother without a second thought, leave him behind when Feliciano would plead for the other to stay.
Ludwig's first thought was there was a small connection missing in Lovino's head.
"We're eating with my brother and Antonio!" Feliciano told him happily. Ludwig had no idea why that would make the Italian happy, but then again nothing about Italians made sense to him. Kiku made more sense to him, and he lived on the other side of the world!
Not that Kiku made much sense.
"Long time no see, Ludwig," Antonio said happily, as if Lovino was not really right next to him. Ludwig would have responded as such (as people were supposed to), but Lovino immediately scoffed.
"Did you have to bring that stupid oaf with you? Useless."
"Lovino!" Feliciano exclaimed, for some reason still surprised at his brother's vehemence. Ludwig had no idea why Feliciano just did not accept it.
"Ah, he just wanted to be the only one with arm candy, isn't that right?" Antonio said as if that was the most natural thing in the world.
Both Ludwig and Lovino spluttered.
Maybe, just maybe, being raised by Antonio forced Lovino to have that personality to survive.
Although it would have been easier if he had just gone along with it.
But Ludwig could not say anything, Feliciano caught him off guard all the time and he never went along with it. Well, sometimes.
And fighting off the Spaniard was something Ludwig had to somewhat admire. It appeared to be difficult and Lovino fought on. Though since it was so obvious Lovino wanted it, it did not make...
But Ludwig did the same thing. It still did not make any sense.
And being called a potato head was getting annoying.
I write this with respects that Ludwig is a bit of a hypocrite. And I do not think anyone else has compared him with Lovino before.
