I haven't watched a Jdrama since forever as I usually find the acting style and script rather cringey.But omg…
Totally get what you mean. I started with jdorama like Long Vacation and Love Gen, but haven’t watched much recently except mostly those starring Satoh Takeru in NF but this one is superlative. Maybe because it’s a combination of Korean production values and Japanese sensibility.
