My guess for seo in is 35

But i counted the lines there were 21 including Youngwoon tho

the bigger strings are the ones merged together which means a bigger number

If you count from the top of the head the number is less than 21, if you count just the ends is 21, there you can see how the merged strings still have split ends

some of them are still merged into bigger strings even at the ends! not like it’s a huge difference but at least like a few more
