Name pls ><

It was a BL manga, and I only remember that the MC and ML were sitting down like on a bench talking (I think they were also eating) when some girls came up and started talking to the ML when then one of the girls told the MC what he was doing there and why was he listening to their convo this made the mc decide that it was best if he left and let them talk but before he did the ML stoped him before them going together, leaving the girls behind telling the girl that the MC was ML’s childhood friend.
