Baby doll narrowed her eyes at her brother, who did not say anything against her sharing a bond close to dom-sub with Young Jae. It was not the first time she behaved like a dom for someone who was not even her sub. But she expected her brother to be displeased at the least.
She knew her brother wouldn't be jealous over this as he understood the reason behind it. But the expected disagreement and displeasure never came. After all, Min Jun was well known for his possessiveness.
Till now, she has had a strong bond with Moon Chin Hae and Henry because of their almost dom-sub bond only. She considers them family, but they listen to her more than their own doms at this point in life.
Dom-sub bond did not always have to be sexual. It could be as strong as a support system to the clueless, lost soul. So Min Jun did not even bother about whatever happened between his sister and his love.
