I believe this three-part "series" consists of scenes that would have been in Why R U? if not for the pandemic. If it is watched alone, it may not make much sense even if the scenes are cute.

It would be fairer to review these three episodes as part of the Why R U? story, which has Saifah and Zon as a side couple. The three episodes here keep up the sweetness and cuteness while also filling in some of the missing gaps in Why R U?, like how Zon overcomes his resistance to his own feelings for Saifah. It is best watched at one go. Ideally, the scenes should be edited into Why R U?, but the audience may not want to watch Why R U again for the missing scenes.

Perhaps there could have been an attempt to inject more to this add-on to Why R U so that it work a bit better as a standalone mini-series, but I guess there are constraints in budget and all. If you've enjoyed the Saifah and Zon segments in Why R U, you will want to watch this for a sense of completion.
