His: I Didn't Think I Would Fall in Love

The same actor plays in here (Kura Yuki) and the atmosphare feels very similar :) You will definitely like this if you enjoyed Kimi no Koto Dake Mite Itai.

Both of these are very subtle and not in your face when it comes to homoeroticism. Showing characters gradually develop feelings, as well as having a girl in the mix to complicate things. The endings are both bittersweet and there are internal doubts in characters in both of these dramas.

In both shows the leads are socially awkward outcasts. They also idolize their popular love interest.

Both dramas are short and tackle the societal denial of what it is to be in a same-sex relationship sensibly and realistically. I love that they both did not exaggerate the idea with campy tropes. Very unlike most BLs. In fact, BL is a hard genre to put these in when they're fully just lovely stories about queer life in spaces that make queerness a non-option.

Both are similar in that the main character moves to a new place and meets a guy there who they end up growing closer to through spending time together, and then falling for. Also, both cover deeper topics as well along the way.

Both are stories of teens coming of age and falling in love, set in beautiful seaside towns. ITSAY is a bit more dramatic and has a lot more going on in the background, but it is also much longer. His is simple, short, sweet and very genuine. Both are very well written and have great conversations about what it is like to fall in love and grow up as a young adult.
