That's my theory too! I remembered they mentioned visiting her grave a few chapters ago, so my guess is that Ho will learn her name at that moment and will like "That's it!"
For me it was just a random thought that came to my mind at the scene when their were writing their names. But with example it would make it so much more sense or more high chance. And visiting the grave with the father! I think Ho and Haebom would take this name to also honour his mom! (๑•ㅂ•)و✧
*with this specific example/clue
Kwon's mom's name has long been the running for what her name will be, that or Sunny
I hope we get to know the baby’s name soon
I can imagine or think that she maybe gets the same name as kwon haebom‘s mom. That would be very cute and wholesome
