Adding a weakness for Solomon

[Vshinobi]

So I was looking at chapter 223 of the manga and in it Arba requests that Sheba marry Solomon and become his pillar of support. Her reasoning being that even though he was a young and highly skilled magician he had a weak spirit and would need Sheba to support him when he is on the verge of breaking down. I think he may have had a very pampered upbring and may not have been prepared for the hardship he may face in the future is what Arba was going along with. For weaknesses maybe we could put weak resolve or spirit. For all his accomplishments and abilities he may have been a weak person or had a weak personality according to Arba. What do you guys think?
