Both Yurumates and Ooyasan was Shishunki take place in a very similar setting- an apartment complex. Both shows are also short series and comedy/slice of life. If you enjoyed the lighthearted comedy in either show you're bound to enjoy the other.
A student moves into a new apartment only to encounter some weird and strange neighbors.
Mahoraba: Heartful Days is a long TV series and has tones of romance whilst Yurumates 3D is a short 3 minute long series filled with jokes.
Both are light hearted comedies surrounding a group of friends.
