Since their first meeting at Martin's wedding, Alexander and Olivia have become much closer, they even meet several times a week even if it's just for casual conversation.
For Alexander, the woman was fun as a friend, moreover she was well-spoken and had many interesting topics to talk about.
Concerning the heart, of course he still has feelings for Anna, but his restless heart always feels guilty for Mayang who he doesn't know where she is.
Martin of course knew that, in order to prepare himself he secretly began to build a power beyond Yustina's reach.
Business marriage is a common thing that happens among the sons or daughters of a large family, especially for people who have interests like them.
Martin needed additional status and power from the Marie family and Alexander needed an equal and far more influential companion to strengthen his position.
