Doomsday: Bro, Lend Me Your Goddess to Boost My Happiness

The apocalypse survival game has arrived, but Chen Jun isn't worried. He has the Happiness Value System Game. He'll rack up happiness points and get ahead of the curve, enjoying the apocalypse to the fullest. [You have activated the Happiness Value System. Improving your shelter's comfort and safety level can increase your Happiness Value.] [Congratulations! Your luck is through the roof. You obtained the uncommon [Low-Quality Security Door]. Your sense of security is through the roof, and your daily base Happiness Value increases by 10.] Chen Jun was speechless. The world's ending, and you're talking to me about happiness? What's the point of Happiness Value? [Happiness Value can be used to upgrade shelters, facilities, equipment, attribute points, and more...] [The [Low-Quality Security Door] can be upgraded to an [Iron-Filled Security Door]. Happiness Value required: 300.] [The [Basic Kettle] can be upgraded to a [Water Purifier] (produces 50 milliliters of purified water per hour). Happiness Value required: 1,000.] "?" "System, I'm really happy. How about giving me some more Happiness Value?" [Host, please do things that make you happy. Don't expect free handouts.] "Things that make me happy?" [You have released a large amount of dopamine. Happiness Value +20.] [You have spotted a woman with stunning looks, a fantastic figure, and an exceptionally high rating. Before the apocalypse, she would have been widely called a goddess. Making a meal with her will earn you 100 Happiness Value. We recommend you make your move.] "?" "That works too?" "Room 520, Apartment 076, Safe Zone. Plenty of food, a soft king-size bed, top-tier security door. Looking for one cute girl. (You know the deal. Freeloaders, get lost.)" "Bro, your goddess smells amazing. Mind letting me farm some Happiness Value with her?"
