Been waiting for thisssss, but let's marinated it a bit.
iirc they eventually went to the fair, and met Shinwoo's ex, then in front of the ex, Han was like, let's remodel outhouse, enlarge our bedroom and put your chair in pavilion. Clasped their hand, and kiss Shinwoo's back hand. He wanted to show off that they're living together
Han also noticed how his height and size similar to the ex, and understand Shinwoo's preference, then he said he'll never watch basketball or volleyball with Shinwoo.
Idk if it's me overthinking, but Yeongwoon eyes look like he's scared. Did something bad happen to him back then?
Jaehyuk, I think you should read this manhwa from chapter 1, then maybe you'll understand why Garam never smile that way whenever you're around.
