I already read that, but I couldn't understand that :(
Can you give me the answer?
<SPOILERS BELOW>
>Go to 3731 at Quarter til Three on Valentines Day, look for Odd Numbers.
You obviously figured out 3731.
Quarter til three = 2:45 -> 245
Valentine's Day = 2/14 -> 214
Odd Numbers 1,3, and 5 -> 135
Next think about when one comes between her nearest neighbors, secrets will be revealed.
Keys 1, 2, and 3 which are in the chests. Put the 1 between the two nearest neighbors, 2 and 3
Translation: 213
