The problem was that while Old Master Shu clearly expressed affection for the younger sister and was very kind to the older brother, he simply ignored him. This was somewhat hurtful.
On the surface, he appeared carefree, like a regular teenager of fifteen or sixteen who didn't care much, but deep down, it was quite upsetting for him.
Before coming, he had mentally prepared himself—whatever Old Master Shu said, he'd just pretend not to hear it.
But unexpectedly... Old Master Shu gave him such a big surprise.
It was clear that Old Master Shu also liked him!
Ruan Jie was overjoyed and deeply moved, his eyes even reddened. He dashed out of the building and ran into the living room of the neighboring building. Seeing Old Master Shu bending over to pour him tea, he flung himself forward and hugged the old man's neck.
"What... are you doing!" Old Master Shu was nearly scared out of his wits.
