Also a lovely BL story without physical lawdness and/or psycho games that many BL dramas will have,
and also has women as positive (and negative lol) part of daily life of anyone in BL - unlike so many BL dramas that make you feel like there are no other kinds of people in the entire world

Similar police drama about a female detective working along with a criminal psychology professor in solving serial murder case.

If you liked Summer Strike, you’ll probably like 18×2: Beyond Youthful Days too, not because they’re that similar, but because they share a similar vibe. Both are slower-paced and focus more on emotions and atmosphere rather than big plot twists. Summer Strike is more calm and healing, while 18×2 is more emotional and can hit pretty hard. If you enjoyed the reflective, quiet tone of Summer Strike, this is a good follow-up, just expect something a bit heavier.
