The thing is in this story, it would be so so much more enjoyable if u stop urself for thinking about morals. IF Wang Xi Yi was honest with his girlfriend it would have been rly rly good. He should call her and properly explain and broke up.

For the whole time i feel uncomfortable becuz if Wang Xi Yi is rly a good man why did he not come clean to his gf when he accidentally slept with Chen Jia Xin. I do not blame Chen Jia Xin when she accidentally slept with a random man she just met on the cruise (i mean, damn girl! the guy is so hot!) but Wang Xi Yi never rly break up with his gf and yet he slept with another woman.
And with all the thing that happen, getting married to Chen Jia Xia, i do not see the guilt nor see him coming clean to his gf who is aboard who he is STILL in a relationship with. If he is not loyal then at least he could be honest. I know everyone like the female lead and the male lead but that does not mean what Wang Xi Yi did is excusable, try putting urself into is gf shoes....Urghhh. Once i consider this point, i truly do not like this type of plot line, its like ur worldview is only one sided. Also, the male lead family, the grandmother, all this time i can't believe she never know her grandson has a gf. So she is demanding marriage to Chen jia xin even when she knew he's with Shi Anna( which she should know cause he has been with his gf for a long time before) why is she demanding marriage to some random girl? Isnt this kinda harsh? So the legit girlfriend unknowingly became the misstress while none of the audience did not think there something wrong with this? just bad taste for me.
