@Takaflame well why shouldn't they? they might share a lover, but that doesnt mean that they are willing to share with every one.
especially with ''angi being cheated'' on before. the core of most of such insecurity is the fear of him being stolen by someone else.
Leon is a awkward guy, he has trouble expressing his affection to said girls. yet is able to do it when talking about them.
also the queen is a married women, has a son his age. and angi`s former boss/mentor. leon was always direct with showing her affection.
