That's My Umbrella (2019) - Region 0

Everything started with the rain, because of the rain - Kondee had to take shelter in the Faculty of Dentistry's building where he met Fahfon. Who came and chatted with him even though Kondee had been avoiding him like crazy, because he once confessed his feeling to Fahfon in front of the whole university! And because of the rain again, Fahfon used it as an excuse to take Kondee home and to the university every day no matter how many times Kondee tried to refuse.
