as much as i love childhood friend type of stories, i dislike how this plot seems forced. no right explanations as to how eiji fell for tatsumi. idk if it's just me but it looks like he just returned his feelings just cause he felt sad or lonely without tatsumi.
Childhood friends Eiji and Tatsumi, who doubted their sexuality, are just friends who have been together. One day, Eiji, who found out about Tatsumi’s “promise of marriage” to someone else since young, began having complicated thoughts… The spring time of life of adolescents boys.
