Hu Tao said: The one who killed the husband who laid in her heart... was me
I still don't get this line
Hu Tao was talking about the 'finality' aspect in funeral.
The woman was saying 'Finally, I can put all of this behind me', as in 'accepting her husband's death' or to be more frank, 'their relations are over'. Since Hu Tao knew that spirits do exist and will still love whoever they left to The Great Beyond even after crossing over, she felt bad for the widow's since the other party will began to forget about their spouse and kept going on with their life.
It's kinda hard to explain, but basically this short comic was playing with the concept 'until death do us part' hence why Hu Tao wanted to see the Traveler to ease the loneliness she felt, because she didn't have anybody else that knew that the spirit will still be around.
No need to thank me...was me...Right.It was a wonderful funeral service...Ah...Thank you for today.The one who killed the husband who laid in her heart...I feel like I can finallyget closure and put this all behind me now.
