A few new entries going into the big list of J-drama Cliches and tropes!
Unexpected Person at the Haka
Whenever a lone character goes to visit a grave and give offerings, he/she will be startled by the unexpected arrival of another person. Then the two will talk about the deceased, usually they employ this method to explain backstory between the deceased and the main character.
Slamming Down a Glass of Beer in Disgust
An almost comically overused cliche of the downtrodden employee who, after going to an izakaya with co-workers after a hard day, will take a swig of beer before slamming it down and half-drunkenly complaining about the “jerk” that they are working with!
Bonus points if the scene begins with a closeup of the glass slamming against the table...
"Hey, There's That Person I Like! Ooops..."
A new variation of the classic "Mistaken Kiss" trope that i've been seeing a lot lately is when the main character is just starting to fall in love with this new romantic interest and sees him/her out in public. They happily rush over to say HI...but stops SHORT when they see the person MEETING UP with ANOTHER PERSON who looks like it is his/her LOVE INTEREST!!
Cue heartbreak and subsequent "OH I SEE He/She already HAS a partner, guess we were only FRIENDS, well, I guess that's OKAY!
