Comments

The ASAS-SN light curve is not a typical SR variable light curve
Is it maybe a YSO with increasing magnitude eruptions? Or a symbiotic variable?
Period search including the latest ASAS-SN data gives 197 days period, but the phase plot is not convincing.
Latest ASAS-SN light curve:
https://asas-sn.osu.edu/light_curves/91ae3e93-0f9f-4ccd-b163-4127390e07fc

J-K=0.65
B-V=1.88
U-B=0.55

Further observations are encouraged.

This is a known variable ASASSN-V J203148.85+403800.1 with 206 days period.
