Kids gonna be named Sunny right? I feel like that’s inevitable

I never thought of that but that would make so much sense O.o

That might how the official translation treats her name, or if the author makes Ho and Haebom give her a separate English name as said in the last chapter. The original title means "the house where the sun rises" and contains the word 해, hae - sun, so I see 햇빛, Haetbit, as a possibly contender in Korean, the native Korean word for "sunlight."
