I found in a It came from Tumbler video
Junko: How do I ask a boy out?
Kokichi: Roses are red, violets are blue, guess what my bed has room for two
Junko: OMG NO
Rantaro: Twinkle twinkle little star, we can do it in the car
Junko: STOP IT
Nagito: Row, row, row your boat gently down the stream, merrily merrily, merrily, merrily I can make you scream
Junko: I feel like the last one is verging dangerously into serial killer territory
None of these are shipping Junko and any of these people, I ship Shuichi x Kokichi, Hajime x Nagito and Korekiyo x Rantaro
They're just helping her with flirting. Even tho all of them were topped.
