Hadan Zentei, Migawari Hanayome wa Katabutsu Onzoushi no Mouai ni Torokasareru

Yuki, who works at a Japanese confectionery shop, has been cleaning up after her older sister's messes since childhood. Then one day, her sister messes up again. Just before a blind date with the son of a client company, she discovers she's pregnant! Begged by her sister, who relies on her for help in times of trouble, Yuki reluctantly agrees to go to the blind date in her place. Although she intends to refuse, the son, Tomoaki, is handsome but so expressionless that it's impossible to tell what he's thinking. He proposes marriage with unbelievably good conditions, but Yuki firmly and clearly refuses...or so she thought...but instead of giving up, she finds herself being tossed around by his unexpectedly sweet advances!?
