MC is a top actor in previous world. Always smiling (the kind of face where it looked like he knows what you are hiding)
ML is a top actor in current world. Serious face but a little tsundere
Flow of the story and its transitions are great. MC is not always saved by ML, only sometimes. MC is also good with words, not like those other manhuas where I don't even understand.
MC died in his previous world due to stomach cancer. He canceled his treatment to go to the temple, in which the monk have him a ring. After he died he transmigated to another world with the ring. MC landed in ML's bathtub where they fought about the ring because ML believe that very ring is the Ji family heirloom.
