Thumping Spike 2 (2016)

its the sequel but with different characters
but the female lead in the thumping spike one had a female lead older than the male lead and the female lead in thumping spike 2 had female lead at the same age or younger than the male lead

Both are set up similarly with 15 (ish) minute episodes.
Both are college romances with entertaining side couples too.
Both are themed around clubs/teams.

The second part to Thumping Spike. The story is different than the first one but still about volleyball teams. I preferred the second over the first. Again no BL so don't watch if wanting that, just purely for volleyball. Enjoyable watch.

1. Lee Won Geun is the main lead.
2. Both have sweet, youthful content.
3. Both have love-triangle
