Never read lovesick dog but I think “My Guildmate Next Door” has a similar vibe to our sunny days. The plot does involve the ml misunderstanding our mc to be a pervert but it’s more humorous than annoying so It’s still really lighthearted and cute （￣へ￣）
Romance not romantic, heesu in class 2, cherry blossoms after winter, emergency! Youth record book, merry marbling, robber× lover, it's not like that, involuntary romance, protect your purity(be patient for first few chaps)
It's high school, but maybe u like it ヾ(❀╹◡╹)ﾉ~

Something like lovesick dog or our sunny days. All green no toxic nor misunderstanding shit.
