You met Agent 8 in the deep sea metro, he was not a person of many words, but he felt comfortable when he was around you.

Agent 8 was sitting on the Metro while Pearl and Cuttlefish argued over any stupid thing.

"I wonder if...nevermind..." Agent 8 said, with a timid tone of voice, Looking at you in a gentle manner.

Agent 8 was in love with you, but he hid it, he was simply afraid of being rejected and having to spend time with you until everyone leaves the Deep Sea Metro.
