Sono Koi, Jihanki de Kaemasu ka?

Traversing the cities of Berlin, Seoul, and Tokyo, a 10-year-long love story between two young men is told. It all starts when Ryu Narutaki, who left everything behind in Japan, is saved by a boxer named Johan Hwang in a foreign land.

in both Can I Buy Your Love From a Vending Machine and Restart After Come Back Home, we see mature love with slow and realistic way, we can see characters' love searching and fear. They've really good acting and everything, emotions make you feel like 'well-done'

Yes, both have mature and step-by-step love but also there's being in a relationship/dating fear, anxiety, actings are well-done

So the setting is quite different, but they both had this very sweet, innocent, first love vibe to it. Like not very eventful, but really sweet to watch.
/Also Seven Days has a sequel that makes it whole, so it doubles the cuteness watching time! :3
