(Sorry for late response) Np, also my profile picture is of 2 boys from an anime (no manga tho) the anime is called "LinkClick". It is ongoing and it's not a official BL, (yet) the 2 boys happen to be the main characters too. The anime is sort of a thriller, mystery series. It involves solving murders, and it does have its fun moment's I promise it knows when to have serious moments and wholesome moments.
The black haired boy: Xiaoshi, his personality is like a golden retriever but he's also very emotional, he has a back story that will bring you to tears (literally I cried). White haired boy: Lu Guang, he's like a black cat, stoic and mentally more mature.
Also, the 2 boys have powers. Xiaoshi has the power to go back in time using photos, Lu Guang has the power to see through the photos (you'll understand more of their abilities if you choose to give the anime a try).
Now, why I 99% sure the anime is going to become a BL. (Also the 2 boys aren't canon YET.) Firstly through the episodes the 2 of them are SO GAY around each other (in my opinion), there would be scenes where Lu Guang comforts Xiaoshi in emotional moments and Xiaoshi seems to be very clingy to Lu Guang. Secondly one of the industries working on the anime is known for making A LOT of romances including BL's, example "Heaven official blessings" (ACTUAL BL). Also the name of the industry is "Bilibili" it might ring a bell.
Also forgot to mention that their is also female character that is best friends with the main characters (she's technically a main character but the 2 boys are more regulated) right now I forgot her name but her and Xiaoshi are childhood friends (in my opinion they act more as siblings so it's a really low chance of her being a love interest), Her and Xiaoshi also fight like siblings too. --
