Milklove is on the first episode of this. It's also a stand-alone sequel to their story from Bad Buddy. It'd be worth giving this a try before/after jumping into 23.5.
If you enjoyed Bad Buddy, especially the characters of Ink and Pa, please watch their special episode in this anthology, "Zero Photography". Just like BB it's super touching, romantic and the couple has great chemistry. So worthy it, and I'm glad it fleshed out their characters a bit more.
This also takes us back to Pa and Ink from Bad Buddy and Korn and Win from Cupid's Last Wish. Although these are an extended product placement ads, but at the core it does feel satisfactory to see these characters again.
