I get why people would rank it high, the show and the characters and the actors were adorable and it was very cute however, in terms of romance the show failed at it.
Even though this show had kiss scenes and they are a bl couple, their relationship was dry and they still seemed like they had a bromance. There was some chemistry but it just wasn't romantic. Like the main character was good at showing he liked him, but when they got together, it was dry and they didn't actually seem like they liked each other anymore. I wish this show gave them better moments together that actually gave off the vibe that they really liked each other and wanted to be partners. It definitely didn't give the vibe that they only wanted to see each other. It was still a cute bl nevertheless. And I would recommend it, but it was disappointing.
