Well thee only time I guess would be in One Piece where during Robin's backstory and it was around the time Robins mother appeared. but I guess that relates to personal issues of mine
I'm watching Sakurasou myself. Guess I'm in for some feels.
OT: Clannad + AS (No brainer), Angel Beats (No brainer), Penguindrum (If you haven't watched why the hell haven't you? :devil, and The Sunday Without God (Came extremely close, I was more eye watering level).
Naruto and OP have come close but not as close as TSWG.
