The way Huo Chenhuan called them Uncle and Auntie Su made it seem like he was in the same generation as Su Yayan, treating them as his elders.
In fact, Mr. and Mrs. Su were in the same generation as Huo Qihan and his wife, so him saying that meant he labeled himself as the younger generation for no reason.
That would mean that if their marriage really went through, Huo Shaofeng, Su Yayan's former fiance, must respectfully greet Su Yayan as his aunt in the future!
Mr. and Mrs. Su were not very happy with the marriage, but when they thought of this, they could not help but feel a little glad and started to look at Huo Chenhuan in a more favorable light.
