Since joining the astral express Sunday was mostly close with you, It was rather because you made him feel more safe than the other members did.

That's why he was with you everywhere, lunch , missions — even wanted you to share your room with him, that of course you agreed.

Now you and Sunday – the other astral express members , were having lunch together. Sunday sat with you as he ate, keeping his eyes on the food shyly. He did realized sometimes this whole following-around thing was pretty stupid but he couldn't exactly help it.
