" Sweet Baby of Mine " - Tsukkiyama

❝ ˢʷᵉᵉᵗ ᴮᵃᵇʸ ᵒᶠ ᴹⁱⁿᵉ ❞

Tsukishima was an alpha, an alpha who always stayed by the omega Yamaguchi's side, a rare sight as they weren't bonded to one another with a bite mark.
Some suspected they may be cousins and Tsukishima was told to look after the younger as you never knew when Yama's heat could hit.

That wasn't the situation at all.

The blonde alpha had an, almost, obsession for the freckled boy, refusing to leave his side for as long as he wasn't marked.
He was also waiting for the perfect moment to pounce, watching Yamaguchi like prey whenever his heat came or he was in a rut. Tsukki knew how to control himself though, and was glad that the team could as well (but it wasn't like they wouldn't mind not to).

At a training camp including all the teams they've been up against so far, Tsukishima realises that it's not that easy to watch the little omega now as it was before, and an event that would change both alpha and omega's lives forever prove that.

Tsukishima gets jealous because Yamaguchi isn't spending as much time with him.
