Korean web comic,[Somehow, my soulmate], episode 4 summary and free Korean vocabulary

Original source [4]

She is hesitant about writing a checklist that the person has to follow during the marriage.
He wrote down three points: “Stop smoking”, “Don’t bully Chwi( the cat)”, “If you have a problem, tell me immediately”.
While she wrote 3 points as well: “Do not enter my room carelessly”, “Do not pressure me”, “If something happens, communicate it”
She became fixated on the point “Stop smoking” because it is a habit that habitual smoker simply doesn’t stop doing.
Even her dad tried to stop her but was unsuccessful.
He told her about his hatred for cigarette smell and asked that she made an effort by smoking moderately.
Apparently she was okay with that condition as she moved the “don’t bully Chwi” point and asked who Chwi was.
She is confused on why the cat would be named “chwi”, which means rat.
He stated that cats like rats, so he named it after rats.
She asked him how he would have handled it, if it turned out that she had a cat allergy.
He responded with “I would have prepared another room for you”
They finally agreed to each other’s terms and signed.
