Fansubbed here = https://nekocap.com/view/c8A15EgHU9
or you can watch directly from YouTube if you already have the Nekocap extension added

From the same team that made the "Be Friends First" saga from the past two years. Episode number is not final, just how many have been confirmed so far.

Ep. 1 = https://www.youtube.com/watch?v=Ze273_9kVTE
Ep. 2 = https://www.youtube.com/watch?v=oYBA4BRAK30

Coming to GagaOOLala on USA, the UK, Germany and France = https://x.com/gagaoolala/status/2022642038634590632

Can also be freely watched (no VPNs, payments or logins required) in the original 40-vertical-episodes format on the Douyin website, but it only comes with Mandarin subs = https://www.douyin.com/video/7544239992722263347

Fun fact: although the official English title on the poster is "Happy", the native title 开心开心 (kaixin kaixin) actually translates to "Happy Happy" BUT, since it's wordplay with the name of the protagonist (Kai Xin), a more realistic interpretation would probably be "Happy Kai Xin"

Now available on Heavenly (Korea-only & pay-to-watch so you'll need a VPN and a subscription to the site) in 20 episodes, since each of them contain 2 of the original eps = https://heavenly.tv/en/detail/1053

The full original version with the 100 eps is available on the StarShort app.
The two YouTube uploads shared before in the comments *are* technically official because they come from content farm channels that are subsidiaries of the same parent company as StarShort, but they're incomplete (for example, the version in the "欣欣甜劇社" channel is missing the first 5 eps and the version in the "LiLi Drama" channel is missing the first 6, plus both are missing many more from the middle of the series).

Quick explanation of these companies' relationship: https://postimg.cc/VdV4c1xb

I'll leave links to all 3 versions in the replies to this comment
