The Shangguan Family never provoked Chen Yuan, and because of Shangguan Yu, their relationship remained rather acceptable, but Chen Yuan was close only to Shangguan Yu.
If it's just because of a word or a person, it probably won't change Chen Yuan's attitude.
This is something Shangguan Yu must mention.
The Five Great Families may be lofty, but it depends on whom they're dealing with. For an ordinary martial artist, marrying a direct daughter of the Five Great Families is certainly reaching high, but considering Chen Yuan's current status and strength, it's the Shangguan Family that's reaching high.
The strength of the Five Great Families isn't actually that formidable. Except for the Gu Family having a Yang God ancestor, the other four families don't have any Yang Gods.
Though their reputation is quite prominent, their real strength isn't as impressive.
