Japanese bl manga

Can you help me find this bl manga
It's Short Seme × Tall Uke
Black haired uke × Blonde(?) Seme
The seme and uke have a small age gap of maybe 2-3 years?
The uke had a huge crush on the seme and the seme like him a little too.
Seme leaves for the college and the uke also tries and gets admission in the same college.
The seme dates guys similar to uke but breaks up eventually.
It's a short happy story.
