Byul lovingly encouraged her husband HaHa to keep his marriage pledge to not smoke.

On February 26, HaHa tweeted, “Is this stress… to quit smoking… can I do it… cigarette… I want to smoke…”

To this, Byul replied, “Honey! Dream’s father!! You can do it! Be strong”, expressing her full support for her husband. Still showing his cravings for cigarettes, HaHa replied back, “I am going crazy! Kuohohohoh!”

In the previous episode of MBC Music's Haha 19TV Mutiny, Byul revealed the conditions she wanted from HaHa like “quit smoking” and “reduce alcohol intake” in preparation for their parenthood.
