Professor Han, however, didn't look at him but walked over to the sofa and started conversing with Su Niannian and Zhang Tao.
Su Haikang stood still, glancing at Su Niannian and then at Professor Han, looking utterly bewildered.
It wasn't just him, everyone in the room, including Old Sir Su, was thoroughly stunned by the scene.
Especially Chi Yan and Su Qing, who watched the scene with their eyes nearly popping out of their sockets!
Professor Han had never been so amiable with them!
For a while, the room was dead quiet, filled only with the sound of Professor Han communicating with Su Niannian and her group.
It wasn't until Professor Han had finished arranging work for Su Niannian and Zhang Tao and let them leave that he continued to return to treat Old Sir Su.
But by that time, nobody's mind was on the illness anymore.
Su Haikang thought for a moment and still decided to go after them, blocking Su Niannian's way.
