It’s a manga and it’s very cute. We follow the mcs through their middle school years to high school to beyond. It’s very sweet and it feels like I was watching them grow up. We watch them grow in height, love for each other and age. Highly recommended!!! ( ̄∇ ̄)

I really want a recommendation for a bl manhwa where the two MCs are pinning for each other for years and they don’t know it. They are oblivious but everyone else can tell. Then they finally get together later on.
