My best feeling was when once I was watching a movie at night on my house with a bunch of friends and my crush was next to me, some time later she said she wanted me say something to me, I was starting to get curious, then she said that she likes me. A true achievement in life. I couldn’t be more happy.
it’s basically someone who will never notice you. in japan it could also mean an upperclassman like fellow classmates of higher level, age or someone you look up to. so once they acknowledge you, you start to get really excited because you are being noticed by someone you admire a lot.
