Where to Watch Heart Stain
- Jim FoxJanuary 31, 2026This is cute and short, easy to binge. However, false-start love stories are not my thing so I struggled with this one a little bit. The ending too was a bit unsatisfying, as if they were leaving it open for a second season that most likely will never see the light of day. But if you want to watch an entire series in an evening, this one will leave you with a 3.5 star feeling.
