Cat Mail Co Heart: Help the Lovers

Lovers’ packages are actually special paired parcels. When you scan them, one package reveals a love heart icon and it requires you to apply the heart (lovers) stamp, find the pairing and ship both together.
This feature ties into a specific achievement and is somehow a puzzle. So, it’s normal if you’ve been stuck. I was confused at first too, but the solution is not that hard.
About the Heart:
Guide to Handling Lovers’ Packages
Before anything, you should have unlocked this heart puzzle. This happens as part of the game’s natural progression, similar to how cold storage and other special parcel types unlock over time. There’s no fixed time for it to unlock. The time depends on how far you’ve progressed through the backlog.

The first parcel can be identified only with that scanner machine. Under the scanner, it shows a love heart symbol. Put a heart stamp on it and then it’s time to find the pairing.
Pairing and Shipping
This is a matching partner package (apparently, there’s no one-sided love in this cat mail world). Ship both packages together on the same boat trip.
A tip I learned: Stack the two packages on top of each other on the shelf or in the boat so you don’t separate them accidentally. If they are sent separately, they’ll return later.

Nighttime Machine Tip (for linking)
After the captain leaves (night phase), it’s time to use that Nighttime Machine. Place the one you identified a heart symbol on it.

Activate the machine (push 1) and follow the lights to the matching package. The lights will highlight the partner package. After finding the partner, ship them together.
One more thing: the matching partner can be any parcel you already have (like one buried at the bottom of a stack in cold storage or a back shelf). Try to keep your parcels accessible rather than deeply stacked, since you won’t know easily which one is the pair until the machine finds it.
Achievement: “Until Shipment Do Us Part”
This achievement unlocks when you correctly identify and process a lovers’ parcel. It can be missed if you overlook the pairing, so keep an eye out once lovers’ mail starts appearing.
Extra Practical Tips

Here are some additional helpful tips. We don’t want to be the reason a lovers’ relationship is ruined, right?
- Organization: Treat lovers’ parcels like fragile items. Keep them together and protected. As I said, nighttime often reveals more clues about them.
- Common Mistakes: Treating relationship flavor text as irrelevant is a common mistake even I made it at first. It can hint at the correct pair and make matching much easier.
