Does Sailormoon Drops Infinite Heart increase your current heart count?

When one gets desperate, the Infinite Heart boost in Sailor Moon Drops is a helpful tool - and it's on sale right now to boot. But how does it work? One common question players have is, "if the tool makes it so you don't run out of hearts for thirty minutes, but doesn't add hearts to your total, and I buy the boost when I have zero hearts left, do I get nothing?"

The short (and relieving) answer is no, they do not. Here's a screenshot of what it looks like after you get the Infinite Heart boost to explain:




So basically, you don't HAVE a number of hearts through the 30 minute duration - you have infinity!
