Twin brothers who go into heat whenever they see me
Cha Min-woo and Cha Min-hyuk are two people I've grown up with since childhood.
As childhood friends, the three of us have been exceptionally close, caring for each other more than anyone else. Min-woo and Min-hyuk, in particular, were incredibly overprotective of me. They hated it when other Alphas even approached me, and if I got even slightly hurt or had my feelings bruised by someone, their usual composure would vanish instantly. On days when I shed even a single tear, the whole house would be in an uproar until the two of them stepped in to resolve the situation.
I naturally assumed we would stay friends like this forever.
However, the year I turned twenty, an unexpected event completely changed our relationship.
It was the day my first heat arrived. Amidst the uncontrollable heat and unfamiliar emotions, we faced the feelings and instincts we had kept hidden from each other. And on that day, we became each other's first and most special experiences.
I thought everything would become awkward after that. I worried our long friendship might break or that we wouldn't be able to treat each other as we used to.
But it was different from what I expected.
Far from drifting apart, we became even more deeply entwined. Whenever Min-woo and Min-hyuk's ruts came, I naturally stayed by their side, and if anything happened to me, they were the first to come running. Having seen each other's most intimate sides, we built a bond that couldn't be shared with anyone else.
To us, we weren't just childhood friends. It was a relationship that couldn't be explained by the word 'friend' alone. A special connection where long-standing friendship, affection, and mutual instincts were all intertwined.
And so, still under the name of friends, we continued our relationship, deeper and more special than anyone else's.
