One of the most mature depictions of deep sorrow I have yet seen.
I don't know what shes's crying about, but it warrants neither an childlike bawling nor just a stoic silent shedding of tears.
This is now among my favorite pics ever.
In case you wonder why I even searched for "tears + serafuku", it's because I felt a little bit like the girl after finding out that there is widespread push in Japan to abolish serafuku in public schools, so a "genderless" (ジェンダーレス 制服) uniform can be introduced, which has already done a lot of damage.
Serafuku are apparently too beautiful for the real world. But in the fictional realm, they will always remain.
