After My Confession, Mr. Gu Directly Took Me to Get the Certificate.

[Marriage first, love later, secret love for each other, 1V1, double cleansing] She and he grew up together. When she was a child, she always liked to follow him, and he took care of her in every possible way. Later, she fell in love with him. The two have a crush on each other, but neither of them dare to pierce the window paper, so they can only keep approaching each other in the name of brother and sister. They are both afraid that one day the window paper will be pierced, and they will not be able to be siblings anymore. Until she got drunk one day and confessed her love under the influence of alcohol. Then within a few days, he took her to get the certificate.
