Iris and Jin Liwei already laid out a plan on how to officially announce their marriage to the public. Everything had been arranged. For now, however, the two of them wanted to enjoy their honeymoon first without any unnecessary interruption.
As for her pregnancy, the official announcement would need to wait longer, perhaps when she reached her second or even third trimester. Or maybe, they would only announce it after she had given birth. Even they weren't sure yet.
Jin Liwei, the proud husband and father-to-be, wanted to announce everything to the whole world but had to restrain himself because his wife had become easily stressed ever since getting pregnant. Although Iris usually didn't give a whit about public opinion regarding herself, her pregnancy hormones made her more sensitive to other people's comments about her worthiness as a mother. This was further exacerbated by her remaining fear of becoming a mother.
