Senku realized the problem but wasn't perceptive enough to know that pointing it out wouldn't be terribly polite.

"I think he's upset with me because I don't want him to hug me." He said wryly. "It's not him, it's anyone."

He glanced at Inigo and shrugged at him, he felt a little bad for upsetting him, but he was mostly perplexed by that. No one else seemed upset about it, unless he'd just missed that which was entirely possible.

"It's not a measure of how much I like or dislike someone. I didn't really hug my dad either."
