[SubDesu]
*12:53 - Dodge (minor, recurring): virus -> substance
17:29 - Nuance (negligible): "I like" -> "I'm in love with" / I usually count "like" in love confessions as mistakes, but the MC is a dweeb and he was panicky so it might actually work here.
*21:02 - Error/Logic (minor): "When I just happened to glanced over during class," / 「何気なく」 is basically "for no reason". She's staring right at him in video, not "corner of my eye".

[GotSpeed]
*5:05 - Nuance (minor): "so nobody even tried to talk to her anymore." / Not really "they weren't able to", they just ignored her.
9:08 - Nuance (negligible): I am personally not liking this "cold from hell" phrasing here. He didn't imply it to be THAT bad.
*11:53 - Liberal (minor): "I feel lighter," / Unnecessary changing of detail to match video.
17:33 - Literal (minor): "Then try to make an approach to me." I prefer "Then try to make a move on me now." / "Approach me" sounds like "come closer".

[IB]
*4:27 - Context/Error (major, arguable): "There was something I personally found to be hilarious," / "Personally" is not "happened to me". This is elaborated later, but it's confusing.
5:05 - Nuance (negligible): "and everyone started ignoring her." / "avoiding" is too strong. They acted like she didn't even exist.
**13:07 - Error: "Your analysis was just so bizzare." / Not the way he said it.
17:19 - Nuance (negligible): "I like" -> "I'm in love with" / I usually count "like" in love confessions as mistakes, but the MC is a dweeb and he was panicky so it might actually work here.
