Wasn't Lee Seo-jin's attitude toward RESCENE a bit off? Honestly?

Even taking into account that they were trying to create funny scenes for a variety show,
I couldn't feel any affection in the way he treated the RESCENE members.
..
It felt like he was being moody and snappy.
It felt like he was being dismissive.
It was so bad that May looked genuinely flustered
and was almost on the verge of tears..
You can tease someone to make things funny,
but it felt like he crossed the line.
It felt like there was no goodwill.
It was to the point where it made the viewers feel uncomfortable..
