If reactions were a thing in V3, I bet we'd get some comments with 500+ reactions under stuff like
Tomo-chan wa Onna no ko! and
Komi-san wa Komyushou Desu.. Those were crazy popular manga.
Here's some other interesting stuff:
Jesus, back then LHT Scans every god damn chapters gained like 200k Viewers and every Wednesday the site broke down because of Solo Leveling. Those alone almost gained Traffic of 4M.
Its believable that it will surely got the most reacted post there.
