The Hamilton family owns 60 percent of the Ellecant group while 25 percent is owned by his family, the Augburn family, and the rest is shared among the rest of other people. Therefore, it is clear that the Hamilton family authority in the Ellecant group is far above them.
Realizing this, the Augburn family encouraged Ron to marry Lilliane, who happened to be the same age as Ron. With Ron's flirtatious nature, everyone including Ron himself thought this an easy task, but who would have thought that Lilly wasn't as gentle as she seemed, she was stubborn, outspoken, and quite opinionated as well, Lilly was also not easy to please and doesn't seem to care about his approach which gives Ron a headache.
On the other hand, his family wouldn't stop asking about the progress of their relationship and blamed him when he gain no satisfaction result.
