Lain Paterson Grades an Infidelity Checklist Live, and the Polite Tone Does Not Last

NIJISANJI — Lain Paterson spent nearly two hours on Wednesday working through an “uwaki hantei,” or infidelity-check sheet, rating everyday situations between a partner and a friend of the opposite sex by how acceptable they would be. The sheet was created by a senior colleague, and she said viewers had asked her to try it during an earlier chat stream.

She began in a measured tone, and said at the outset that the exercise was about how she would feel if the other person did it, not about viewers’ own conduct. The first item, a lunch for two with an opposite-sex coworker, drew a quick flare-up. Paterson argued that anyone with a partner could simply decline, then caught herself and apologized for getting heated. She called the lunch not cheating, but something she would still dislike, and weighed it at roughly 2.5.

“Be careful not to be swayed too much by a partner. It’s your own life, so keep your regrets few.” — Lain Paterson, near the end of the stream

The pattern repeated. On an outing for two with a friend the partner already knows, she went from questioning why it needed to be just two people to listing the ways it could become a date, imagining a pair at a movie holding hands over a tearful scene. Midway through the sheet she said she had slipped into the wrong version of herself, a nod to the polished and unvarnished answers she had prepared. Daily messaging with an opposite-sex friend, late-night calls and compliments such as telling someone they look cute today each got a similar treatment: not cheating in her view, but unwelcome. She settled on a 2 for one item after saying she was losing interest in the imaginary partner she was addressing.

Other items drew milder verdicts. She said a birthday gift exchanged out of courtesy, sympathy for a friend who is crying, or lending a jacket to someone cold were understandable, and that noticing a new haircut was a good habit, though she wavered on how it would come across. On a second and third page she was firm about shopping trips, karaoke and theme parks for two, saying she would join in or suggest bringing others. Items about former partners received a more forgiving reading, and she said congratulating a former partner on a new relationship was reasonable.

Chat answered in kind throughout, with viewers noting how quickly her tone changed. Paterson closed by telling viewers not to let a partner dictate their lives. She said a dance-cover short collaboration would go up on her channel at 8 p.m. that day and that she would not stream the following day because of a long recording session.
