When Phobos saw her beam at him as brightly as a thousand watt light bulb and come running towards him, he slowed down. He needed a moment because that kind of reaction wasn't one he got very often.

The blond wasn't one who evoked happiness and that was why it always felt like a punch to the gut when it revealed its face to him. Very much like Adrestia's 'I'M SO HAPPY TO SEE YOU, FUCKER!' blows or kicks to the stomach. Having Harmonia wrap her arms around him without hesitation, squeezing what little air remained in his lungs out with her slender arms, effectively declared his 'moment' over.
Wrapping his arms around her, he squeezed her just as tightly and brushed a light kiss against her temple. "Yeah, you like it? I washed it with expensive soap," he replied, grinning, as he pulled back to look at her face. The flutter in his stomach and the light dizziness made him feel a bit like an idiot but he didn't mind being turned into one by his sister.
