These two may not know but he knew how difficult it was for the siblings to run away from those people back then. He could still vividly remember the scene from more than a decade ago. The day he saved these siblings from the clutches of those people. The conditions in which he found them haunted his dreams for years and he still had nightmares about that day occasionally. He did not have the heart to let those siblings face those demons again. Not until they were fully prepared to face them at least.
Seeing Grandpa's expression Li Yang knew that he finally understood the gravity of this situation so he gave them another plan instead, "How about it, rather than a party we will have a small family dinner and invite the siblings to the dinner. This would be better than throwing a party and we will also get to talk freely."
