The top picture is Mizuhito when he was little. The bottom one is a young Yuriko with Majima.
OMG these pictures are so adorable <3 It’s so fun imagining what they were like when they were young and the times they spent together. But I can also imagine the… PAIN both Majima and Mizuhito went through at this time too and… *cough no more spoilers* Anyways, these are really sweet <3
