(Xiao Lan recalls)

Shinichi catches up with Lan and pulls Lan's arm.

Shinichi: You are really too much trouble.

Lan: What?

Shinichi: You are a tough case. Even if I were Sherlock Holmes, I couldn't solve it. I must correctly guess the heart of the girl I like. . . .

Shinichi: You said love is 0? Stop laughing. You tell the grass queen that 0 is the beginning of everything. If we don't start there, nothing will start. Nothing, remember to say it.
