Both are Thai BL dramas that include Mean, Plan and Perth in the cast. It's not directly connected to the Love by chance universe but it has connections with Love Sick (Noh and Phun are part of the story as well)

Thai BL dramas with multiple couples. The main similarity is that in both, one of the lead characters is abandoned by their boyfriend since the first episode (Pete left Ae, Pha left Wayu) and they have to overcome their sadness with the help of their friends.

Alice in Borderland is has the similar set up where a bunch of people are made to fight to survive and are not sure what their purpose is. It's also got a modern vibe, but doesn't have the GARO universe aspects.

Also adaopted from a manga, and about a death/survival game where participants are trying to find out what's behind the game. Gantz is more gorey and features aliens similar to Alice in Borderland's isekai feel.

Both are psychological, with a lot of play around trust, relationships and mystery. In both, they end up trying to figure out what is behind the situation (Alice and the games vs the class and the weird sensei)

Although TBFS is a movie while ITSAY is a series, both have some similarities. Both pertain to high school students and teenage love between the main actors. Also, one of the main characters is initially reluctant to express his feelings toward another guy.

both talk about "extraordinary" creatures, and both deal with nose bleeds/headaches and how they're related to those unknown "enemy" though unlike the waterfall blood in sweet home, circle only had drips

Isa Pa with Feelings also tells the love story between a hearing impaired and a hearing person. Gali teaches sign language and asks Mara to be his partner in a dancing contest.
The story is very relatable and Carlo Aquino is convincingly acting as a hearing impaired.

Paen Rai Long Tai Wa Rak is modern, but both the female leads pretend to be pregnant to search for clues. Both are comedic and the ML's families are welcoming to the FL.

Ossan's Love is also a Japanese BL that takes place in an office setting and has a manga-esque comedic style. Similar to Adachi, the main character in Ossan's Love finds out a colleague (or two) has feelings for him and his ordinary work life becomes hilariously complicated.
