If you see this review and u wanna see this series but you don't know where to watch it? U can absolutely watch it at Tiktok/Douyin, Youtube & Bilibili/Bstation. Because this is mini series( it's just one minute per episode ) so in that platform it must be gathered. So i give this series 9.5/10 because it's really good. i absolutely recommended this mini series to you because that great acting, chemistry, etc. But yeah the problem just less duration & the platform to watch. ( anyway u search it with keyword "summer love letter" and it will pop up that video.
Thank me later
