I just don't feel the love at all. I want him and Jun to work things out, but there's no affection to found anywhere. Their good times are only alluded to. They never look happy together. It's so depressing.
It's not like I expect them to be a super lovey-dovey cringy couple that's constantly all over each other. But the author doesn't even show a shred of affection. When Jun says "I love you" I literally don't believe it.
