Sairjeon
Despite being arranged, Y/N put in a lot of effort in her marriage. Jimin being a reserved man didn't care about what she did. Slowly and steadily he did catch feelings for her. After all, who wouldn't fall in love with such a bubbly, cheerful, and sweet girl? Things go haywire the day he plans his confession.
Time as they say is the best medicine, heals everything. One fine day, Jimin finds a diary. Oblivious to Y/N's feelings, he begins to read her diary and gets to know her more intimately.
