A psychological trauma.

Chen Lihua blushed when she heard him say 'he wanted to relieve himself', because she understood what he meant. 

So she hurriedly wore her trousers before running off to the bathroom. 

Seeing her run away in fright, Liu Longwei smiled to himself. Then he heaved a sigh of relief before looking at the bulge. Shaking his head pitifully, he condemned himself for seeking for trouble for no just course. 

As he was in discomfort, he had no choice than to bear it till Chen Lihua came out, in which he rubbed her head affectionately before running into the bathroom to settle his problem. 

Chen Lihua stared at his back for a while before walking towards her bed to lay down.

Liu Longwei took some time to settle himself.

And by the time he came out, he was met with the sound asleep Chen Lihua.
