Use your daily free spin of the Secret Love Affair Gacha. Don’t forget to spin it! Free Affection items to help you get those special scenarios/illustrations/bump you into good endings. Since this walkthrough will be not 100% for a while, I recommend that you always play your gacha to get extra affection!
Use the Linn Gacha sparingly. You use Linn to spin it. But, you also use Linn in the game to clear missions. I’d suggest resisting the urge to spin it a lot unless you plan on using platinum to clear missions.
Login daily. Even if you don’t have time to play, just make sure you open the app and go to ‘My Page’ in order to get your daily login bonus.
Max out your friends and greet them daily. At least for your first route. You’ll soon get to a point where you’ll have too much money and it’ll start to mean nothing.
Every day do something for platinum. Whether it’s installing an app and opening it or going to a website and looking around, you’ll need it at some point to bump your affection up or if you want to get premium avatar items. I’d hold out for affection, you’re going to need it to bump yourself into the good ending
