This is a Children icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
There is a simplified drawing of two people holding hands. The one on the right is presumably male and the one on the right appears female based on the clothing. The female is wearing a dress and pigtails, the male looks to be wearing shorts.
